Each species is a WPA-style illustration, generated with an AI image model conditioned on real reference photographs — the references anchor the plumage, markings and proportions so the art stays accurate. Every reference below is Public-Domain or Creative-Commons licensed; the photographers are credited with links to the original. (A few species may still show a historical public-domain plate until their illustration is made.)
Species pages show photographs from iNaturalist, contributed by the photographers below and used under the Creative Commons licences shown. 743 photographs across 127 species.
