I think this is a ring-billed gull:
Yellow eyes with red rims, black wing tips, yellow legs, ring around the bill.
And this would be an angry swan:
With a bone stuck in his throat. No wonder he's upset!
And a bittern:
Nose in the air.
Well, I never get to see a bittern, even when other people find them right where I've just been. So I may as well make do.
