What is one Sahara mammal amphibian bird and reptile?

A bird is the ostrich, a reptile is a frog, and a mammal is a gerbil

Um.... first of all, a frog isn't a reptile, and secondly, i doubt a gerbil and an ostritch live in the Sahara. I say a mammal is a goat, a bird is the Eygyptian Plover and an amphibian is a FROG.
