Are you a sexist birder?
Do you favor male birds, preferring bright masculine colors?
Are your female ID skills weak? Do you slide past female birds because, well, they are harder to identify?
You're not alone. Birding is rife with sexism. It's what we've been taught by books and science, whether we knew it was happening or not.
Look at Roger Tory Peterson's earliest field guides (I have a second edition, 28th printing, 62 years old). His warbler illustrations, among others, place male birds foremost, in front of females, the former partially overlapping the latter.
A newer edition (2020) gives each sex its own space. David Sibley in his guides does the same. National Geo guides make female ID clear. Newer books tend that way.
The issue touches more than books, however. In England in 2019, Mya-Rose Craig, an ornithologist and birdwatcher with the birding blog Birdgirl, asked the Royal Society for the Protection of Birds (RSPB) why its posters showed female birds in sizes smaller than their male counterparts.
Was this the result of sexism? she asked. The RSPB promised to review its posters.
