I reblogged this a minute ago but I’m going to reblog it again, because I want to add another non-binary bird species: the ruff.
First of all, look at it.
That’s a male ruff, specifically. You can see how they get their name. The females don’t have that fancy collar. They just look like sandpipers, which is what they are.
Like other sandpipers, these are wading birds, but they live in wet meadows and marshes instead of by the seashore. During the breeding season they gather together and the males hold territories, called leks, in which they display to attract females.
At least, some of them do.
Some male ruffs do not display in leks. They have plainer, often white, neck ruffs, and they sort of wander around the display grounds courting the females wherever. The interesting thing is that the territorial males tolerate this. Research suggests it’s because females are more interested in a display ground that has both kinds of males. The ladies like variety, it seems.
But it gets even more complicated. In 2006, a third male form was discovered. This form is extremely rare, and doesn’t have male display plumage at all. It looks just like a female ruff in the field. The other birds, however, can tell the difference, judging by their behavior. These female mimics travel with other males when the sexes split for the winter, and during homosexual mountings (which are common, as they are in many other animals), they often top.
What’s really interesting about these ‘cryptic males’, or faeders, is that they are apparently super sexy. Seriously. Females and males both prefer mating with them. And it’s believed that, like the satellite males, the presence of a faeder attracts more females to the area, which benefits all three forms.
And the thing about these forms is they are fundamentally different from one another. The plumage and behavior differences last throughout a bird’s life, and are determined by genetics. They are functionally three different genders - one of which shows natural intersex characteristics. All three can breed with females, and females are more interested in breeding when all three are present. They know that diversity is the good shit. Which makes them much, much smarter than TERFs.
