We have a 24 year old scarlet macaw - my husband got it a long time ago, long before he knew me. You can't tell a boy scarlet from a girl scarlet without a dna test, and it didn't really matter to us, so we just always referred to the bird as a "him" - his name is Erasmus, and Erasmus was a guy, so it was as good a guess as any.
In the middle of the night (it felt that way, but was probably in that nether space between when/if teenagers go to sleep and when we do), one of our sons burst into our room saying, "Raz laid an egg!"
And he, um, she, did. The now known to be feminine Raz has been sitting on an egg all morning, turning it, and being rather protective of it (scarlet macaws can be dangerous!) She's going to be disappointed as she is our only macaw, so nothing will hatch from that egg. And we don't really need to add to our menagerie, so fixing that problem is not on the agenda.
So now we need to find a girl's name that has a nickname of Raz...
And wonder why after 24 years, this bird would decide to start laying eggs.
