That...isn't right. Birds don't perch on Infrastructure. Or at least, normal birds don't perch on Infrastructure. It's not worth the hassle of being run off by angels on patrol--Hajime knows, he'd done it from time to time himself as an angel--so why is the bird there?

He starts breaking out the zoom lens. It's a good way to get a better look at the bird, maybe a few pictures of it, before he goes after it head-on.
