Simply put, birds are evolved from small dinosars, and dinosaurs belong to the same group that crocodiles belong to, archosauria, while turtles belong to the group sauropsida, because, while they appear to be more similar to crocodiles than birds, the evolutionary common ancestor they share is far more ancient, unlike that of crocodiles and dinosaurs. That's evolution for you.

∙ 8y agoIt is a product of evolution. Birds and crocodiles are the only living members of a group called archosaurs. Archosaurs first appeared in the Triassic period and soon diversified into a number of groups, including crocodiles and dinosaurs. Birds evolved from a group of small carnivorous dinosaurs in the late Jurassic.
