Wow! That is an impressive aviary!! Just look at all of the Black-crowned Night-Herons perched on the rafters on the right side! It looks like flocks of Spot-billed Ducks, Mandarin Ducks, Black-crowned Night-Herons, a few White or Oriental Storks (not sure which), Gray Herons, one of the species of cormorant, and maybe Great or Intermediate Egrets in the trees on the left. And I'm sure there's a lot more that I can't see!
