I’ve searched high and low for the wonderful original post because this is amazing and deserves to be rebloged but I hope this is good enough.
As thundercrumbs said GET OFF THAT MANS FACE!
Hoatzin (Opisthocomus hoazin) aka “Stink Turkey”, family Opisthocomidae, order Opisthocomiformes, Peru
The only living member of the bird order Opisthocomiformes.
This leaf-eating bird uses foregut fermentation, in its enlarged crop, to help break down its food. (The ferementation is where the smell comes from, which gives it the name “Pavo Apestoso”)
They live in vegetation at the edges of lakes, streams, and rivers.
The young have 2 small claws on the fronts of the wingsthat help them climb through vegetation.
