My wife and I have been watching these magpie Jays for a while and I was just wondering what if all would be the purpose of the plume on their heads. It's strange in it's a single strand with a few feathers. The blue jay in North America has a plume on its head as well but it's more complete.
I'm sure the reason is just for attracting the female but was wondering if there was another reason since it seems so specific instead of just brightly colored feathers like other Male birds have.
