Berlin Zoo

This is probably the best zoo I've been to. Clean, clearly signposted, well-maintained and room for most of the animals (birds excepted but they always seem to get a raw deal).
Panda:

Okapi (probably the finest backside in nature - with one possible exception)

Polar bears...



This is Knut, by the way: the controversial polar bear cub. Bigger and grubbier now than some of those cutesy images, eh?

All manner of other stuff too, but you'll have to wait for the full download for the details won't you.
