More than 300 Wingspan fans submitted artwork of their favorite birds in the game for the Wingspan Fan Art Challenge, and 255 artworks were selected - each by a different artist - in a variety of styles. The end result is a large set of bird cards, mechanically identical to their counterparts in Wingspan and the Europe, Oceania, and Asia expansions.

The box for the cards is designed for both storage and reusability. The cards fit in the bottom layer of the Nesting Box. You can mix the cards with your standard Wingspan set, select some cards to replace the cards you have (there are a total of 446 unique bird cards in Wingspan), or play games only with these birds (their percentages correspond to the percentages on the bonus cards).
