Birds are actually the only living relatives of the dinosaurs! They're warm-blooded reptiles whose scales have been adapted into feathers and whose bones have gotten stronger and lighter. Birds come in all shapes and sizes, from the tiny shrike seen above to the huge, flightless ostrich. The class Aves includes two of my favorite animals, the barn owl and the crow.
