Birds of the world
Birds started evolving from theropod dinosaurs about 165 million years ago before the breakup of Pangea, so are widely spread across the world. From Penguins in Antarctica to Parrots in the tropics and Eagles in the mountains they occupy all environments and niches and come in a staggering variety of colours. Perching Birds and Parrots seem to have originated around the time of flowering plants over 100 million years ago in Australia when it was part of Gondwana .
