Theropod dinosaurs, based on fossil and genetic evidence. Theropods share skeletal and anatomical features with birds, suggesting a common evolutionary ancestor. This hypothesis is supported by discoveries of transitional fossils, such as Archaeopteryx, that exhibit characteristics of both dinosaurs and birds.
Birds, which are not just considered descendants of dinosaurs; they are dinosaurs.
scientists believe birds detect changes in the temperature and daylight as days get shorter and the amount of light decreases, birds produce certain hormones that seem to trigger the drive to migrate
Scientists believe birds evolved from dinosaurs because of several pieces of evidence, such as shared skeletal features, fossil records of "transitional" bird-like dinosaurs, and genetic similarities. These connections suggest that birds are the descendants of a group of small theropod dinosaurs.
Robins were birds of forest clearings, as were bluebirds. Scientists believe that since the eastern forest was mostly cleared, these species are more common today than 200 years ago.
Scientists have found a number of fossils of theropod dinosaurs with anatomy remarkably similar to that of birds. Many dinosaurs are now known to have had feathers.
Chickens are birds, which scientists believe descended from the dinosaurs. So, in a way, yes, chickens are dinosaurs.

flying reptiles are in fact birds. as animals are now being classified into monophyletic groups, we must include birds as reptiles as well because they came from a common ancester
