This is a White-Headed Buffalo Weaver isnt it? Had no idea Chester still had these guys, this is taken in the African Aviary presumably - how long have they been there? I havent noticed them before...
First time I've seen them too, and I had no idea of the ID, but now you've given me an clue, Google seems to confirm that - thanks! And yes, it is the African/Tsavo aviary.
I think we concluded they were a new addition to the aviary (as of this week), I haven't seen them there before either.
