Hoo Hoo

We popped into the zoo again this afternoon. Very quiet, and went round everything in the one-way system without crossing paths with anyone. Didn't need to touch anything, and had a nice stroll. A lot of the mammals were sleeping, but quite a few birds were chatty. This Turkmenistan Eagle Owl is so cute. He just sits there and the very deliberately says "Hoo" - like a person badly imitating an owl! Then again: "Hoo". Or is it Who?
