Hammerkop

This Tropical bird at the Calgary Zoo (in the Transalta Rainforest building) is called a Hammerkop. I wasn't expecting it to suddenly come quite so close to me and, what with juggling with people walking by and trying to wipe my lens that had misted over in the humidity, I missed getting the complete head! The bill is quite a bit longer than you can see here. Also, the eye should be brown, not red as seen here. Quite a strange looking bird.
