The idea of making a game about the birds of the UFES (Federal University of Espírito Santo, in southeast Brazil) campus was a sum of long-brewing factors. I have always been interested in the souvenirs offered to people at natural parks, zoos, aquariums, shrines and other similar spaces, especially when regarding the biodiversity and the landscapes of the place. It is beautiful? Funny? Cheap? Does it have educational value? I always asked myself these questions in search of a souvenir that pleased my biologist and traveler self.
In 2016 I was able to spend a few months in the USA, where I visited several natural parks and of course, brought back many souvenirs and ideas. With the end of my degree in Biology, my advisor Viviana Borges (who had some experience with natural parks in South Africa) and I put the ideas together and decided that I would turn a campus bird survey I had done at the beginning of my degree into a game of collectible cards. Then, SuperAves was born.
In the game, each card represents a species, containing its popular name, scientific name, and some features of the bird species it represents, such as: weight, size, year of description (“discovery”), number of eggs it usually lays, its geographic distribution in Brazil, and a bit of trivia. The cards are bilingual: in Portuguese and English.
The game starts with all the cards in a pile, and each round all players take one card and keep it to themselves. In each turn, a new player chooses one of the characteristics of the card that he believes to be superior to the card of other players. Whoever has the highest value for that trait wins the round and obtains the other players’ cards. In the next round, new cards are taken from the pile, and that’s how it goes until the end of the game, where the player who accumulated the most cards is the winner.
In addition to the common bird cards, there are two instructional cards (one of rules and one explaining what each bit of information on the cards represents) and one special card that beat the others, called SUPERAVE. Naturally, it is important that, as an educational tool, the teacher or mediator who applies the game clearly explains that one bird isn’t better than another.
In the Biology events where I presented the game, everyone asked how much it costs! – which makes me very happy, since it means that people liked it so much, they are willing to pay! At the moment, as the initial production demands a certain investment, I only produced a pilot deck, but I am looking for a partnership with the regional public power (so that the game could be distributed in public schools), and with the private sector too (like zoos , aquariums, etc.), proposing customized versions of the game for each of these locations, while I continue to improve the layout of the game.
We hope this game will increase students’ interest in science and biology, facilitate learning about biological diversity, zoology and even ecology, and bring back some interest in the natural world from the lay public, which seems to have decreased over time. The game can be easily played (and collected) by children from 10 years old, or when they become able to read well, as well as by teenagers and adults, students or not. The important thing is to want to have fun and to get to know a little more about nature (in this case, birds).

 “Aves” is not only a general term for “birds” in Portuguese, but also the scientific Latin name of the group: Class Aves contains all avian dinosaurs.
Birds have fascinated humankind since forever. Their ability to fly, besides being a constant reminder of our own limitations, was a clear starting point to link birds to deities and the divine realm (Bailleul-LeSuer, 2012). Inevitably, these animals became very pervasive in all human cultures, myths and folklore (Armstrong, 1970). In fact, they are so pervasive that they have found their way to perhaps the most unlikely cultural niche: Heavy Metal.
With some exceptions, such as raptors (Accipitriformes) and ravens/crows (Fig. 1), birds are not typically seen as badass enough to feature on heavy metal album covers and songs, even though sometimes they already have the right makeup for it (Fig. 2).
As we highlighted above, the birds’ power of flight is their main feature, but they have another power up their feathery sleeves. And this feat is one that people tend to consider one of the most human endeavors of all: music. Most birds are deemed melodious creatures, like the slate-colored solitaire (Myadestes unicolor) from Central America and the celebrated nightingale (Luscinia megarhynchos), although some might seem almost tone-deaf (Fig. 3).
Birds (class Aves) can be largely divided in two groups: the order Passeriformes (with circa 6,000 known species) and “the rest” (several orders, totaling around 5,000 species). Members of the order Passeriformes are commonly called “passerines” or “perching birds” and include most of the species that typically comes to mind when we think of birds: sparrows, robins, starlings, blackbirds and crows. Inside Passeriformes, there is a suborder called Passeri, the “songbirds”, a group with roughly 5,000 species of animals. The vocal organ (called syrinx) of songbirds is modified in comparison to that of other birds and can produce complex sounds (Raikow & Bledsoe, 2000). Typically, these sounds result in bird song, but crows have their own way of communicating.
With all these bird species, some are bound to appear in heavy metal songs, right? We mean, besides eagles and ravens, of course. So, we decided to analyze the lyrics of thousands of metal songs in order to find ‘em birds (Fig. 4).
Here, we show how many songs talk about birds and which specific birds they mention. We also investigate how each bird groups is represented in the genre and in each subgenre. We will also talk a little bit about the biology of some of these animals to make you, our dear headbanging reader, more acquainted with this fantastic slice of Earth’s biodiversity.
MATERIAL AND METHODS
All lyrics used in this project were collected from Metal Kingdom (www.metalkingdom.net), a web compendium on metal music of diverse genres. To collect this data, we built a custom web crawler that navigated all music pages on the website. This collection yielded us three main datasets:
Bands: CSV file listing all bands found on the website.
Genre: CSV file mapping bands to their respective metal genre.
Lyrics: CSV file which contains the actual lyrics, as well a reference to the artist.
On 07/August/2018, we collected a total of 145,716 songs from 6,359 bands, spanning 368 different metal (sub)genres.
When we started going through the data we obviously ran into some problems. (If you’re not finding any problems in your data, you’re not looking hard enough!) In this section, we present some of the hurdles we had to overcome when working with this dataset.
A quick look into the data showed us a problem for our study: not all lyrics were in English. For example, below are the verses of “Ohne Dich” by German band Rammstein (2004):
“Und der Wald er steht so schwarz und leer,
Weh mir oh weh,
Und die Vögel singen nicht mehr.”
We may have some additional language skills to identify ‘die Vögel’, but we certainly won’t know every language in the dataset. Because of this, we decided to restrict our study only to songs in English. However, this posed another problem: we have no structured data about the language of each song, and this information would need to be inferred from the lyrics themselves.
Fortunately, this was also a problem for Google when deciding in which language you’re searching in during your queries, and they were kind enough to opensource their implementation. They used a Naïve Bayes approach, which achieved 99.77% accuracy when classifying news articles in over 49 languages (Nakatani, 2010). Using this approach, we managed to label almost all lyrics by language, identifying 43 different ones in the corpus. The distribution of the languages can be seen in Table 1.
This method, however, is not without its own problems. We were curious, for instance, as to why there were so many lyrics in Romanian (ro). A more in-depth investigation revealed that instrumental songs would have only the text “(instrumental)” listed as their lyrics –the algorithm struggles when classifying such short words. However, since this problem affected only songs without lyrics (that is, songs that won’t mention any birds at all) we opted to just remove them from the dataset.
Another problem we identified was homonyms: words that sound and are written the same, but have different meanings depending on the context. Consider, for example, the following excerpts:
Song: White Synthetic Noise Lyrics
Band: … And Oceans
Band: A Perfect Circle
Sorrow sings of everything but survival doesn’t seem to ring
Isolate, contain your pain to outlast the taste of misery
Show the stars and I can clear the air and love the end
Red flag red, all the sentinels are damned
The Tokyo kitty, swallow, rose, and canary
Tick tick tick, do you recognize the sounds as the grains count down
Trickle down right in front of you?
The word ‘swallow’ has clearly different meanings in these songs. In the former, it is a verb, that is, the act of causing or allowing something to pass down the throat. In the latter, however, we have a reference to a Hirundinidae bird that may or may not be able to carry a coconut.
To address this problem, we must distinguish between the different uses of homonyms. One way of doing this is classifying each word in a text by its Part of Speech. A part of speech is a category in which a word falls given its syntactic function in a sentence. In the first example above, ‘swallow’ is classified as a verb, while in the second example it is classified as a noun. Since we are interested in identifying mentions of birds in lyrics, knowing that a word function as a noun in the sentence can help us reduce the homonym problem. (Unless, of course, they are nouns for both their meanings. In this case, this approach won’t help much.)
The process of classifying words like this is known as Part-of-Speech tagging, or POS tagging in short. POS tagging can be seen as a supervised learning problem, as we can train a classifier to identify these tags given a pre-labeled dataset of token sequences and tags. For this project, we opted to use a pre-trained model available in NLTK. This default English POS-tagger consists of a Greedy Averaged Perceptron implemented by Honnibal (2013).
Let’s see how this works for our examples. POS tagging on the first one yields the following result:
The tags are represented by abbreviations from the Penn Treebank Tagset. In this case, we can see that ‘swallow’ was assigned the POS tag ‘VB’ (Verb, Base Form) and as such, should not be counted as a bird. Let’s see how this works out with our second example:
Here, ‘swallow’ was assigned the POS tag ‘NN’ (Noun, singular or mass) and as such, should be counted as a bird. However, this example also shows that this method is not perfect, as ‘canary’ received a ‘JJ’ tag (Adjective). However, since the alternative would be to manually annotate POS tags for the whole corpus, we decided to proceed with this alternative.
With both language and homonyms out of the way (well, sort of), we can finally tackle our last problem: plurals. Consider the following two examples:
Song: For the birds
Band: 8 Foot Sativa
Band: A Static Lullaby
To close my eyes
Reduce you to black
Nothing more than an insignificant shadow among the vultures
I will walk away
Scavenger, where does the vulturesleep?
And when you speak to him
Will you bring him to me, bring him to me
Scavenger, bring forth the jackals teeth
We can see that both songs mention the bird ‘vulture’: the first one uses the plural form while the second uses the singular. We wanted to count both references as the same bird, so how could we achieve that?
One solution would be to increment our list of “bird terms” to include all plurals of bird name, as well as a mapping to a root form of the word. This, however, would be a lot of work. This looks like a common problem when doing natural language processing, so we searched for what we could do to address it.
Lemmatization is the process of removing inflectional forms, finding the root word, that is, the lemma, so that they can be analyzed as a single group. It is widely used when running searches for terms in documents as a way to correctly match-related terms. Fortunately, there are various lemmatizers implementations for different languages. For this problem, we will use the WordNet lemmatizer available in the NLTK library.
Lemmatizer usually requires the POS tag of the word, but fortunately, we got that covered. Running the WordNet Lemmatizer in our first example yields the following: “Nothing more than an insignificant shadow among the vulture.”
You might be thinking: “Wait. That much work just to take out an ‘s’ from the end of the word?”. However, remember that grammatical number can be way more complex than that (e.g., goose and geese), and using a proper lemmatizer takes all that complexity into account.
OK. We detected the language of our metal songs and filtered only those in English. We tagged the part-of-speech of all our words, and we even lemmatized them to ensure consistency. What is then left to do?
Well, we need to count our birds! For this project, we decided to use a static list of bird names commonly used in cultural works. The list can be seen in Table 2.
We only counted the term in our dataset if the POS tag of it corresponded to a noun. This reduced the likelihood of homonyms such as ‘swallow’ bird and ‘swallow’ verb, but unfortunately will do nothing for homonyms such as ‘tyrant’ flycatcher (Tyrannidae) and ‘tyrant’ Cersei Lannister. The count was done in two different ways:
Occurrence counts: This method counts the number of times a word appears, counting multiple repetitions in the same song as distinct occurrences. For example, when counting the word “bird” in the classic song “Surfin’ Bird”, by The Trashmen, this counting method would yield 82 occurrences.
Song counts: This method counts the number of songs in which a word appear, counting multiple repetitions in the same song as a single occurrence. Keeping with our previous example, “Surfin’ Bird” would only wield 1 as the count of the word “bird”.
To validate our methods, let’s take a look at the top 5 most metal birds:
That corresponded with our expectations, even though we probably are suffering from a homonym problem with all those tyrants showing up. The tyrant flycatchers are not actually that metal (Fig. 5).
We also grouped our bird count by each metal genre. In this way, we will be able to run an analysis on how different birds relate to different types of metal. Given that we had 368 different metal subgenres, we had to summarize this if we wanted to run any meaningful statistical analyses. We summarized them using the definitions from Wikipedia into “just” 37 categories, listed in Table 3.
RESULTS AND DISCUSSION
The word ‘bird’ appears in 2,222 songs, as we’ve seen above. It seems quite a lot, but on a closer look, it’s not quite: that number represents only about 1.5% of all the songs in the database. We honestly didn’t know what to expect when we started this project, so it is hard to decide if that’s a lot of birds or too few of them. We are more inclined to the latter, given that birds are such prominent symbols in most worldwide cultures.
But more specific mentions of popular bird names also appear in several songs. Some likely refer to a single species, like ‘nightingale’ (Luscinia megarhynchos) and ‘blackbird’ (Turdus merula). Most common names, however, refer to a whole group of species, like ‘eagle’ and ‘penguin’, and not to a particular species in each group. Finally, some common names, like ‘dove’ and ‘swan’, while being representatives of larger groups, in this context probably refer to the most common European forms, the rock dove (Columba livia) and the mute swan (Cygnus olor).
We present below the number of times each type of bird is mentioned in a metal song and we do this in two ways. Table 4 shows the total count (the “occurrence count” from the example above), which includes all the times a particular word pops up in the lyrics. As explained above, this includes repetitions within the same song, such as in chorus sections. For instance, ‘eagle’ appears several times in Helloween’s “Eagle Fly Free” (1988). Table 5 shows the counts ignoring all the repetitions (the “song count” from the example above). This way, ‘eagle’ is counted only once in Helloween’s song.
We think the second type of counting (Table 5) is a better representation of bird abundance in metal songs, so we will only refer to this one in our discussion below. However, if should be noted that eagles are the most used bird according to Table 4, but they come in second in Table 5, having switched places with ravens. Even though we knew from simple life experience that these two were the most metal birds, we expected eagles to get the crown in both types of count.
So now we can say with certainty that the most metal bird is the raven (Fig. 6). The word can refer to several species worldwide, but it is logical to assume that people usually think of the common raven (Corvus corax; Fig. 9) when using the word. This species is distributed throughout the Northern Hemisphere and is one of the largest passerines alive. Ravens are omnivorous animals, extremely opportunistic and versatile, and their intelligence is well-known to biologists.
Ravens are undoubtedly one of the most common birds in folklore and pop culture but are generally regarded as birds of ill-omen and related to “evil stuff”. Thus, they are well-represented in Black and Death Metal, with respectively, 328 and 152 occurrences. However, they are sometimes associated with nicer things, like the ravens from the Tower of London (Kennedy, 2004) and Nordic mythology. The relationship with the latter is very clear given the 114 times this bird appears in Pagan Metal songs.
In second place, we have the eagle, a staple of Power Metal and original Heavy Metal (Fig. 1), with 197 and 193 counts, respectively. Eagles are very likely the most prominent bird symbol of all in Western culture (Armstrong, 1970): Zeus, the Roman Empire, European heraldry (especially Germany and Austria), and of course, ‘Murica. As the “king of birds”, the eagle is almost always a symbol of power or leadership. The ‘eagle’, however, will not be the same bird species for every headbanger: American bands and fans will always think of their national symbol, the bald eagle (Haliaeetus leucocephalus), while others will possibly think of the golden eagle (Aquila chrysaetos) or other more regional species. Eagles are part of the Accipitridae, family together with hawks, kites and Old world vultures (see below); however, the name ‘eagle’ is given to several large species that are not actually too closely related to each other (e.g., booted eagles, snake eagles, sea eagles, harpy eagles; Lerner & Mindell, 2005).
The third most used bird is the vulture. This term does not refer to any specific vulture species, but most likely to a sort of over-generalized stereotypical representation of a vulture in popular imagination. Vultures suffer from a bad press, being often mindlessly associated with corpses, death and decay due to their scavenging diet. Unsurprisingly, it is a prevalent bird in Death and Black Metal songs, with 228 and 143 counts respectively. Trash Metal also has a good number of counts (117), but given this genre’s more political lyrics, ‘vulture’ is here often related to bad people or practices.
The popular name vulture actually refers to 23 species worldwide, distributed in two distinct yet closely related biological groups (Buechley & Sekercioglu, 2016): the Old World vultures (Fig. 7) and the New World vultures (Fig. 8). Old World vultures belong to the family Accipitridae, the same as eagles and hawks, while the New World ones (which include condors) comprise the family Cathartidae. The scavenging habits of vultures evolved independently in these two lineages and in both cases has led to some common adaptations to this way of life: large bodies and wings, powerful beaks and featherless heads (Buechley & Sekercioglu, 2016).
The fourth bird on our list are the crows. Again, ‘crow’ can refer to any out of 30-something species. The typical European black crow is called carrion crow (Corvus corone; Fig. 10); the hooded crow (Corvus cornix) is also very common in the continent, but it is not entirely black and so possibly unsuitable for metal songs. North American headbangers will be typically more familiar with the American crow (Corvus brachyrhynchos).
Note that all these species belong to the genus Corvus and, in fact, so does the raven (see above). People get confused about these birds all the time and often use the words ‘raven’ and ‘crow’ interchangeably. While neither word has any true biological meaning (that’s what scientific names are for, after all!), we will give you some pointers as how to differentiate the common raven from those crows. Also, after reading this, try checking all those raven and crow illustrations on heavy metal albums – you’ll be surprised how many of them are just plain wrong.
There are several differences to keep an eye out for when trying to identify crows and ravens (BTO, 2013). First off, ravens are huge, with a wingspan similar to a buzzard’s and an even larger body. If you’re uncertain about the identity of the bird you’re seeing, it’s probably a crow. When you finally encounter a raven, you’ll immediately know it. But there are other features that might help you out if the animals are seen far off, flying or just through photos.
Crows have a rounded head, with the plumage arranged neatly on the body; their beak is deeply curved and stout (Fig. 10). Ravens have very long and heavy beaks, ruffled throat feathers, a barrel-like chest and a long neck, which together gives them a heavy-headed impression (Fig. 9). In flight, crows beat their wings more heavily and their fan-shaped tail is clearly seen (Fig. 10). Ravens, however, tend to soar more; the feathers on their wing tips looks more like a raptor’s when flying and they have a long and wedge-shaped tail (Fig. 9). Finally, crows have a far-carrying “caw” vocalization, while the ravens’ calls are a deep and hoarse croak.
There are some unexpected results. For starters, we imagined hawks and falcons would rank higher on the list, as well the nightingale, which is typically associated with song and poetry. We also have lots of mentions to ducks, geese and chicken, but a good portion of them refer to expressions (e.g., sitting ducks) or, metaphorically, to people.
However, there were some actual surprises. From the list of bird “species” we initially came up with (Table 2), we had included some oddballs just to be thorough and have all avian orders represented. To our surprise, however, our search came up with some occurrences for them, like penguins, ostriches, macaws and toucans.
The song Ostrich, by American band Gloomy Grim (2000), focuses on the fallacious idea that ostriches (Struthio camelus) bury their head in the sand to hide. They do not. What they are doing is inspecting and caring for their eggs; they dig shallow nests and from a distance, it might look like an ostrich has its head buried in the sand (American Ostrich Association, 2019). In fact, ostriches have no need to hide; besides being the largest living dinosaur and having a mean kick, they are the fastest animals on two legs (Donegan, 2002; Stewart, 2006).
All mentions of penguins come from a single Swedish Black metal band called Satan’s Penguins. Several of their songs stick to the theme, such as “Antarctic Winterstorm”, “Behind Mountains of Ice”, and “Night of the Penguins”. Despite being thought of as birds from the icy wastes of our planet, most penguin species live in sub-Antarctic or temperate areas (Davis & Renner, 2003). Actually, the Galapagos penguin (Spheniscus mendiculus) is endemic to the Galapagos Islands, very close to the equator.
Battle of the genres
One curious thing to see was how each genre has its own favorite bird (Table 6). However, when we looked more closely at these results, they are entirely expected. Eagles are the stars in genres such as Heavy, melodic, Power and Speed Metal, while ravens dominate the Gothic, Folk and Pagan genres. The preference of owls in Electronic, however, is a mystery to us.
We could also check which genre is the most biodiverse, that is, which genre cites the largest number of bird “species” in its songs (Table 7). The undisputed crown goes to Death metal, with 46 species; after it, we have Power, Black and Heavy Metal all clustered together with 41, 40 and 39 species, respectively. However, this might just be an artifact of the sheer number of Death Metal songs: this genre has twice more songs in the database (a total of circa 46,000 songs) than the second genre (Black Metal, with circa 23,000). So the change of a bird popping up in a Death Metal song is just higher because of this. (Also, several species are mentioned just once and birds are not mentioned that much in their songs; see also Table 8.) The other three genres we mentioned are better balanced: Black Metal has 23,000 songs total, as shown above, while Power Metal has circa 17,000 and Heavy Metal 22,000.
The least ornithological genre is Grunge, but one could rightfully argue that “grunge’s not metal” or “who cares about grunge anyway?” So the least ornithological true genres are Dark Metal and Christian Metal (Table 7).
However, if you take into account the proportion of songs that mention birds (Table 8), Pagan Metal is the true bird-loving (or should we say raven-loving?) genre. Around 13.5% of Pagan Metal songs mention some sort of bird. The second place goes to Folk Metal/Rock, with 11.2% of songs mentioning birds. The least bird-friendly genres are Alternative Metal (1.7%) and Glam (1.9%).
And what about the songs that have the most birds? Well, we have two worth mentioning, one from a big name in metal and the other from, well, a rather obscure band. First is “The Crow, the Owl and the Dove” by Finnish symphonic metal band Nightwish, from the album Imaginaerum (Nuclear Blast, 2011), later also released as a single (Fig. 11). As expected from the title, there is a good avian diversity in this song: besides the three titular birds, there is also mention of the swan. The second song is “Proverbs of Hell Plates 7-10” by Norwegian black metal and avant-garde metal band Ulver, from the album Themes from William Blake’s the Marriage of Heaven and Hell (Jester Records, 1998). This song mentions the peacock, eagle, crow and owl.
We have certainly been surprised by some of our findings: from ravens overtaking eagles to the odd penguin and ostrich popping up in some lyrics. As we’ve argued, birds are very diverse group of animals, and several species are deep-seated symbols in cultures worldwide. So maybe it’s about time heavy metal left the tropes of ravens, eagles and vultures on the bench for a while and let other avian stars shine (Fig. 12).

Henrique Soares is an engineer and machine learning enthusiast, not particularly knowledgeable in either birds or metal. When he is not working on unconventional applications of machine learning, Henrique spends his time wondering how could there be people that don’t know about the bird, because everyone knows that the bird is a word! A-well-a-bird, bird, b-bird’s a word, a-well-a…
João Tomotani is a mechanical engineer currently working with Supply Chain. Though he is more of a power/melodic metal enthusiast, he agreed to focus on birds instead of dragons in this research.
Dr. Barbara Tomotani is a biologist and the only one in this group whose work actually focuses on birds. She is not a big heavy metal fan and does not work with heavy metal birds, preferring the tiny flycatchers. But she has certainly liked the new metal bird Corviknight.
Dr. Rodrigo Salvador is a zoologist who lately has found himself working with a lot of bird-related stuff. One of the first songs he remembers ever hearing as a child was Walk of Life, by Dire Straits – his sister’s “fault” and an influence that eventually led him down the road to metal. He’ll quickly tell you his favorite bands are Queen and Avantasia, but he’s hard pressed to decide his favorite bird.
 We excluded ‘tyrants’ from the analysis due to the homonym problem presented above. Likewise, we excluded ‘roller’, which is typically used in the term ‘rock n’ roller’ rather than referring to the members of family Coraciidae.
 We confess none of us had the slightest idea Ulver even existed.
Wingspan is a game entirely about birds and it has been a wonderful surprise, being considered one of the hottest titles for 2019. This is the first game from designer Elizabeth Hargrave, published by Stonemaier Games, and will be available in March this year.
In this game, the players take the role of bird enthusiasts (researchers, birdwatchers, and ornithologists) and must discover and attract birds to their wildlife preserves. In board game terms, Wingspan is an engine-building game, that is, a game in which you have to establish an effective system to generate and accumulate points. There are 170 unique bird cards in the game and, as you add them to your nature preserve, they help you do more and more on each subsequent turn. In general, forest birds make you better at getting food, wetland birds help you get more cards, and grassland birds make you better at laying eggs.
The Journal of Geek Studies interviewed Elizabeth Hargrave to understand how ornithology and ecology made their way into a board game. You can read the full interview below.
Q: To come up with a game based on birds, you must be a birdwatcher or an ornithologist, is that right?
A: Yes, I’m an amateur birder.
Q: When did your interest in birds began?
A: I’ve always been a nature lover and appreciated birds in general when I saw them, the same way I appreciated any other wildlife. I’ve always had a bird field guide and a pair of binoculars around. But I didn’t really start intentionally birding – like, going out with birds as my primary purpose – until maybe 6 or 7 years ago.
Q: What gave you the idea for a bird ecology game?
A: I felt like there were too many games about castles and space, and not enough games about things I’m interested in. So I decided to make a game about something I cared about.
Q: Did you bring into Wingspan some of your experience with birds? Your favorite species, maybe?
A: I tried to get a diverse set of birds from North America into the game, and a lot of the common ones. But some species definitely got a push just because I like them. Roseate spoonbills are only in a tiny corner of North America, but it’s the corner of North America that I grew up in, and I love them, so they’re in. There’s a lot of room with 170 cards – but it’s still only a fraction of all of the species that live in North America.
Q: So, let’s turn to the game now. What is the players’ goal in Wingspan? How does one win in a bird game?
A: You win by having the most points. A lot of your points will come from playing the birds themselves, but you can also get points by laying eggs or by using certain bird powers. And then there are specific goals and bonuses that change from game to game. You might have the “photographer” card that will give you bonus points for birds with colors in their name, or the “falconer” that gives points for predator birds. And then there are shared goals that you can compete for, like having the preserve with the most eggs in it at the end of a round.
To win, you usually have to choose to focus on some of those things over others. And you need to think about how the different powers on the bird cards could help you get there.
Q: The game’s strategy is spun around a lot of ecology. What sort of information have you brought from the real world into Wingspan? Or, better put, how much scientific data have you included in the game?
A: There is a ton of real-world information on each card. Birds get played into certain habitats on your player mat, based on their real-world habitat. And each card’s cost is food, based on some very simplified categories of the food that the birds actually eat. And each bird’s nest type could play into the end-of-round goals.
When I could, I tried to work in real-life bird behavior for the powers on each bird. For example, predator birds go hunting by looking at the top card in the deck: if the bird has a small enough wingspan that the predator could eat it, you get to keep that card and score a point for it. Nest parasites like brown-headed cowbirds get to a lay an egg on another bird’s nest when another player lays eggs. That kind of thing.
And finally, each card has a little factoid on it about the bird, and a very simplified map of which continents it is native to. Those don’t actually come into play on the game, but sometimes they might explain why a bird’s power is what it is.
Q: Do you hope the players will learn something about the birds by playing Wingspan?
A: I hope that it’s a game that you can play primarily as a game, without feeling like you’re supposed to be learning anything… and then maybe accidentally pick some things up along the way. A lot of educational games feel very preachy to me, and that’s not my intention. But I do hope that as players interact with the birds in the game, some of the real-world information that’s there is interesting to them.
Q: Suppose a player is inspired by Wingspan to do some birdwatching of their own. Would you have some tips to offer to this fledgling birder?
A: Find a list of common birds for your area, and look for them right around where you live. Once you have a few birds that you can reliably identify, things get easier.
A pair of binoculars makes a huge difference. You don’t have to spring for a super-expensive pair right away – there are decent starter pairs for the cost of a board game. But it’s incredibly frustrating to try to ID birds without being able to see all their markings.
Find a local birding club, or hit up a birder friend – most people are happy to share their knowledge, and to have you along as an extra pair of eyes. I once caused a major freak-out in a group of more-knowledgeable birders by saying “hey, what’s that one?” – it turned out to be a golden-winged warbler, a beautiful bird that very rarely visits our area.
Download the eBird app and keep lists of the birds you see. If you’re anything like me, growing your personal list will be addictive – but you’ll also be contributing to a worldwide database that ornithologists use to track trends in bird populations.
Q: Do you think ultimately Wingspan can help with bird conservation efforts?
A: As much as the industry is growing, board games are still a pretty niche hobby. But every little bit helps! I have definitely heard from gamers who have started paying attention to birds in real life because of Wingspan.
Q: Is there any takeaway message you’d like the players to get from Wingspan?
A: I always set out to make it a fun game first, about something that I love. If you have fun playing Wingspan, my mission is accomplished. If you can see why people love birds – or get interested in them yourself – after playing, even better.
ABOUT THE TEAM
This is the first published game from designer Elizabeth Hargrave. Bird art is by Natalia Rojas and Ana Maria Martinez Jaramillo, while art for the player mats and birdhouse dice tower is by Beth Sobel. Christine Santana did the graphic design. David Studley designed the solo version of the game, with help from the Automa team. Jamey Stegmaier managed the whole team, and worked with Elizabeth to develop the gameplay.
The video game Overwatch is Blizzard Entertainment’s new hit, released on May 2016 for Microsoft Windows, PlayStation 4 and Xbox One. In the game, the so-called “heroes” spend most of their time trying to kill each other to secure a payload. While the morals of these self-proclaimed heroes are rather open to debate, one of them at least has some redeeming personality traits. The hero Bastion is a nature-loving animal-friend robot. Actually, the single animal to appear in the whole game (besides the hominids, of course) is Bastion’s pet bird, called Ganymede (Fig. 1).

Ganymede’s design is an original creation of Blizzard’s artists, although it resembles in shape and size a northern cardinal, Cardinalis cardinalis (Linnaeus, 1758), a common species in Canada and the USA. Cardinals usually have a red plumage (Fig. 2A), but there are rare naturally occurring yellow mutants, called xanthochroic cardinals (Fig. 2B). Ganymede also has a white area around its eyes, a trait not seen in cardinals, but well-known from species of the genus Zosterops (commonly known as “white-eyes”; Fig. 2C), which live in tropical Africa, Southeast Asia and Australasia.

Despite being based in an American species, Ganymede seems to be native to European forests. The bird appears on its home forest in the animated short The Last Bastion (from August 2016), which takes place in the outskirts of Stuttgart, Germany. There is no bird here in Stuttgart that looks like Ganymede (one of us lives here, by the way). Actually, in the whole European bird fauna, only the golden oriole, Oriolus oriolus (Linnaeus, 1758), comes close to it, with its yellow color and dark horizontal stripe across the eyes (Fig. 3). However, its slenderer body shape, thinner beak and lack of crest are all very different from Ganymede.

Moreover, in the Eichenwalde stage (which, in the game’s lore, is located nearby Stuttgart), there is a painting resting above the hunting lodge’s fireplace (Fig. 4). This painting shows four local bird species; one of them is the “Ganymede species”, while the others seem to be actual species: the Eurasian blue tit (Cyanistes caeruleus (Linnaeus, 1758)) and two titmice. The latter are American species and seem to represent the tufted titmouse (Baeolophus bicolor (Linnaeus, 1766)), even though one of them is more bluish in color.

As we pointed out before, Ganymede’s design is an original creation and does not represent an actual species, although some of its features might be traced to the cardinal. Despite the problems with Ganymede’s identification, Bastion’s bird friend can also appear in the guise of actual real-life bird species. To do so, the player must simply equip a “skin” for Bastion (”skin” is basically the gaming jargon for “outfit”). By changing Bastion’s “skin”, Ganymede’s appearance may also change.
The common and rare skins (alongside the legendary Overgrown skin) do not change Ganymede’s appearance, but the epic and legendary skins do. Here we identify all the bird species that most resembles Ganymede’s look and tell a little bit about their biology.
GANYMEDE’S MANY GUISES
Let’s start with the “proper” red northern cardinal, Cardinalis cardinalis (Fig. 5A). This species belongs to the family Cardinalidae and is also commonly known as redbird, being easy to identify due to its color, black “mask” and crest. Ganymede appears as a male cardinal (females are light brown). These birds eat mainly seeds, grains and fruits, but feed their young with insects. They are found from Belize and Guatemala, through Mexico and eastern USA, all the way to Canada. The species was introduced by humans in other American states, like California and Hawaii. Cardinals are common in residential areas and visit bird feeders. They were prized as pets due to their bright plumage and song, but thankfully now have full legal protection.
Next, we have Ganymede appearing as a blue jay, Cyanocitta cristata (Linnaeus, 1758) (Fig. 5B). This species belongs to the family Corvidae (ravens, crows, jays and magpies) and has a distinct color pattern. As a matter of fact, the color pattern of Ganymede’s wings is a little bit simplified when compared to the actual bird’s complicated gradation of colors. Blue jays can be found in central and eastern USA and Canada; they eat nuts, grains and small invertebrates. These birds are typically monogamous, pairing for life; genders are similar in plumage and size. Blue jays are very intelligent, with complex social systems.

Bastion’s two “wooden” skins are fittingly accompanied by a Ganymede looking like two species of woodpeckers (family Picidae): the red-naped sapsucker, Sphyrapicus nuchalis Baird, 1858 (Fig. 6A; although it is also reminiscent of the pileated woodpecker, Dryocopus pileatus (Linnaeus, 1758), and the downy woodpecker, Dryobates pubescens (Linnaeus, 1766)) and the Arizona woodpecker, Leuconotopicus arizonae (Hargitt, 1886) (Fig. 6B). The sapsucker, as its name implies, drills hole in trees to feed on the plant’s sap, also eating insects that are attracted to the sap. These birds can be found throughout the Great Basin region and the Rocky Mountains, in North America. The Arizona woodpecker has a more restricted range, occurring in the southern parts of Arizona (obviously) and New Mexico, USA, and in western Mexico. This species feed mainly on insects (especially beetle larvae), but may also eat fruits and acorns. Similar to the case of the blue jay above, the color pattern on Ganymede’s head, chest and wings are very simplified in relation to the real animals. Also, there is some divergence in color: while the male Arizona woodpecker has a red crest, Ganymede has a yellow one, which makes him more similar to female woodpeckers.

The last two of Bastion’s skins are based on steampunk designs. Therefore, they needed a more city-dwelling bird to accompany him. Ganymede thus appears as a rock pigeon, Columba livia Gmelin, 1789 (family Columbidae), the common pigeon we have in large cities. The Gearbot skin has a common rock pigeon (Fig. 7A), while the Steambot skin is accompanied by an albinistic pigeon (Fig. 7B). We judge it is an albinistic (instead of a leucistic; see Box 1 below) bird, because the beak also does not have the usual black pigmentation (it is pinkish yellow). We could not check if the same is true for Ganymede’s legs, though, as we have yet to unlock this very expensive skin in the game.

Unsurprisingly, all the birds above are American (Blizzard’s headquarters is in California). As explained above, the depictions are not completely true-to-life, but simplified in some instances. This is to be expected, we guess, since the game’s developers would not need focusing too much on a scientifically accurate depiction of a bird. They would rather be more worried about making all the shooting fun. Nevertheless, it seems the team at Blizzard clearly put a lot of effort in making Ganymede, as not only his appearance but also his movements in the game are all very realistic (the model for Ganymede in the animated short The Last Bastion was done based on the pet parrot of a Blizzard employee). The two pigeon “skins” for Ganymede even change his body shape to make him look like a pigeon.
Box 1. Albinism and leucism
Both albinism and leucism are genetic variations, meaning they are conditions defined by the genes the animal inherits from its parents. Albino animals show a complete (or partial) absence of the pigment called melanin in their skin, hair, feathers, scales, cuticles and irises. Melanin is responsible for brown and black colors. Thus, albinos are very light-skinned, with white hairs and red eyes (the lack of pigment in the eyes means that the light is reflected by the blood vessels). This failure to produce melanin is usually caused by the absence or malformation of an enzyme involved in its production. Common albino animals include white lab rats and mice and rabbits. People with albinism are also rather common.
In leucism, however, there is only partial loss of pigmentation. This means paler hairs (or feathers, etc.), often “creamy” in color, but with no changes to the eyes. It is also different from albinism in another regard: leucism is a reduction in several types of pigment, not only melanin. Leucistic peacocks are very commonly bred in captivity and leucistic lions are a fan-favorite in zoos.
On the opposite side of albinism, there is a condition called melanism. The over-deposition of the black pigment melanin in hairs (or feathers, etc.) results in very dark animals, like the black jaguar.
MALE OR FEMALE?
Nevertheless, despite all the care in making Ganymede, there are some major inconsistencies (besides the whole “American-bird-in-German-forest” issue discussed above). Until Gamescom (in August 2016, when the animated short The Last Bastion was premiered), we supposed that Ganymede was a male. This was based on: (1) the name, which is a male one (originally from Greek mythology); (2) it is crested and colorful, which is common of male birds, while females often have a plainer look; and (3) it sings a lot, which is also a typical male activity in birds (usually used for defending territory or courtship).However, in the aforementioned animated short, Ganymede is building a nest, which is typical female behavior. It is very rare for male birds to do the nest building (this is only seen, for instance, in species of weavers and megapodes). Moreover, Bastion’s Overgrown skin, which relates to the short, has a nest with eggs place on the robot’s shoulder (Fig. 8). Needless to say, only females can lay eggs. Moreover, the incubation and hatching is usually also done by females; male birds only rarely incubate eggs. Of course, the eggs from the Overgrown skin are way too large (Fig. 8) to belong to Ganymede anyway.

Ganymede’s sex is never directly alluded to in the game or official material, although sometimes we could find the pronouns “he” and “his” referring to it on Blizzard’s websites. Curiously, the same is true for Bastion, who is almost always referred to by the pronoun “it”, but sometimes by “he”.
The player can also customize Bastion’s victory pose, which is shown after the match if he/she was part of the winning team. One of Bastion’s poses is called Birdwatching, because, well, he is watching his bird (Fig. 9).
It might sound surprising to some that birdwatching is not only an actual pastime but a very popular one at that. But what exactly is it?

Birdwatching, also called birding, is basically an activity of wildlife observation, where you go out to observe, of course, birds. You can do this, of course, with the naked eye, but it is better done with a good pair of binoculars (or sometimes a telescope). It’s a hobby that actually attracts a huge lot of people (Fig. 10), especially when a rare bird is involved. There are, of course, guides for beginners explaining everything about how to start birding, like Birding for Beginners: A Comprehensive Introduction to the Art of Birdwatching (by S. Buff, 2010), and websites like All About Birds (by the Cornell Lab of Ornithology).

After you’ve started your birding campaigns, you will want to know the names of the birds you’re seeing. To identify the bird species, you can use one of the several field guides and handbooks in existence. These books have drawings and/or photos of the birds, with guidelines to identify them. These guides are usually restricted to a single country (or sometimes just part of it, if the country is too large, like Brazil or the USA) or continent (like Europe). It’s very easy to find one at your bookstore or online store, since they are often called “Birds of Somewhere” (Fig. 11). Of course, there are now also websites that act as these guides, such as the RSPB’s Bird Identifier (see References below).
Figure 11. Examples of “bird books”, with the covers of Birds of Australia (by K. Simpson & N. Day, 2010, 8th ed.), Birds of Venezuela (by S.L. Hilty, 2003, 2nd ed.) and Collins Bird Guide (by L. Svensson et al., 2010, 2nd ed.).
Moreover, birdwatching actually involves a lot of hearing, because you will most often hear the bird before seeing it (if you see it at all). Thus, it is also good to know what each species’ vocalization sounds likes. There are several websites to identify birds’ calls, such as the Smithsonian’s Guide (see References below). Of course, both for image and song identification, there are now lots of apps, such as eBird Mobile, BirdsEye, Collins Field Guide and Bird Song Id, among several others. Unfortunately, these websites and apps are still largely restricted to the USA and Europe, while the greatest (and some would say most splendorous) bird diversity is found in Australasia and tropical America.
Birdwatching is all about enjoying nature and having fun, but birders worldwide abide by a “code of conduct” of sorts (see, for example, the code of the American Birding Association). Nowadays, our more ecological-prone society is concerned about the impact that our activities have on the animals and their environment. Thus, birdwatching etiquette usually includes promoting the welfare of birds and their habitats, limiting the birders’ impact (photographing, using playback devices, keeping your distance from nests etc.) and thus mitigating the stress caused to the animals. Basically, have fun, but let the birds live their life – that’s what Bastion does anyway.
