Description:
Accipiter cooperii (Bonaparte, 1828) - Cooper's hawk feeding on a blue jay (Aves, Passeriformes, Corvidae, Cyanocitta cristata) on the western side of Newark, Ohio, USA on 29 January 2014 (photo by Mary Ellen St. John). Note that another blue jay has just dive-bombed the hawk. Classification: Animalia, Chordata, Vertebrata, Aves, Falconiformes, Accipitridae Birds are small to large, warm-blooded, egg-laying, feathered, bipedal vertebrates capable of powered flight (although some are secondarily flightless). Many scientists characterize birds as dinosaurs, but this is consequence of the physical structure of evolutionary diagrams. Birds aren’t dinosaurs. They’re birds. The logic & rationale that some use to justify statements such as “birds are dinosaurs” is the same logic & rationale that results in saying “vertebrates are echinoderms”. Well, no one says the latter. No one should say the former, either. However, birds are evolutionarily derived from theropod dinosaurs. Birds first appeared in the Triassic or Jurassic, depending on which avian paleontologist you ask. They inhabit a wide variety of terrestrial and surface marine environments, and exhibit considerable variation in behaviors and diets.
