So we asked our great guest, Emma Cox, biologist with the Institute for the Bird Populations, what they look like.

Among swallows, these guys are unique because they have a really bright white forehead.

And so you'll see that that's completely unique among our swallows here.

And so you'll see that poking out of the nest.

You'll see this like big, almost, I don't know, little bald cap.

Like a star on their head.

Oh, that's so cute.

into Grass Valley.

Emma, how typical is this?

It varies, but sadly not as uncommon as we'd like it to be.

So I think that I do think Sanju's had a particularly difficult time, but we hear far too often of people who their endometriosis isn't understood.

Maybe some employers don't want to talk about it because they're embarrassed.

And I think because we have, you know, it's a taboo subject around periods.

There can also be issues with bowel problems, heavy bleeding.

And quite often it's just swept under the carpet because people find it embarrassing.

What's your thought on this?
