This species of pelican is known for the shape of its beak, which resembles that of a shoe (hence the name). It has a brownish plumage in a very peculiar shade at birth, which turns gray with age — sort of like humans if you think about it. It lives in Central Africa, but unfortunately, it has been recently added to the list of threatened species. Adult birds of this species have been heard uttering a sort of “moo” sound, like a cow.
