birds whose existence defies gender essentialism

bilateral gynandromorph northern cardinal! the left side of this bird’s body is female, and the other side is male. they can still hypothetically reproduce, as birds (mostly) only have one functioning ovary, on the left side!

bilateral gynandromorph rose-breasted grosbeak! the same case as above, just a different species.

chickens. just all chickens. they can just defy our boundaries of sex.

the white-throated sparrow, which is considered to have four sexes!

the ruff, which also has four distinct sexes! their breeding behavior is really unlike any other bird

ducks, which can also change appearance to show plumage associated with the opposite sex!
this is really just a jumping off point since birds don’t conform generally to human expectations for sex and gender - which is fair since they’re often pretty arbitrary!
