Most paleontologists regard birds as the only clade of dinosaurs to have survived the Cretaceous Tertiary extinction event approximately 65.5. Modern birds are characterised by feathers, a beak with no teeth, the laying of hard shelled eggs, a high metabolic rate, a four chambered heart, and a lightweight but strong skeleton. All birds have forelimbs modified as wings and most can fly, with some exceptions including ratites, penguins, and a number of diverse endemic island species. Birds also have unique digestive and respiratory systems that are highly adapted for flight. Some birds, especially corvids and parrots, are among the most intelligent animal species. A number of bird species have been observed manufacturing and using tools, and many social species exhibit cultural transmission of knowledge across generations.
