Hoatzin claws

Segment from BBC on hoaztin chick claws. Edit 03/2015: This is from BBC’s The Life of Birds - To Fly or Not to Fly? Narrated by the fabulous David Attenborough of course. When I uploaded it, I think you could see the tags so that’s where I included the pertinent info... when they were hidden so was the program info. I uploaded this for an extra mark in my Comparative Vertebrate Anatomy course a few years ago - we got a bonus mark if we found a clip the prof could use in future lectures :p, but it had to be a YouTube video... what a pain in the ass!
