Yes. Scientists believe that the ancient ancestors of several modern birds were around during the latter part of the Cretaceous period. Originally, scientists thought that only aquatic birds, such as ancestors of the loons, seabirds, and albatrosses populated Earth during prehistoric times. More recently, ancient bones resembling a modern parrot have been discovered. As more bones have been found and confirmed, scientists have concluded that certain birds also flew when the dinosaurs roamed Earth about 65 to 70 million years ago.
