Hoatzin
Opisthocomus hoazin
"Gaby, this bird is quite cool and normal looking. Why is it on your blog?" Well my friend, because evolution thought it would be funny if it gave this guy the digestive system of a cow and claws! Yup. This bird eats mostly flowers, leaves, and green stuff. But unlike most birds, when it starts to digest its food, the bird starts to smell like manure. Yum! Because of the weird shit that goes on in its intestines (literally), the hoatzin isn't all that good at flying, but it tries. As for the claws, well when they are chicks and they feel endangered, they'll usually jump out of the nest into nearby water, swim out, and use the claws to climb back up. So yeah, thats pretty much what separates the hoatzin from your average bird.
