modern birds
Today's feathered creatures
Modern birds are the avian lineage that survived the mass extinction 66 million years ago, distinguished from their dinosaur ancestors and extinct relatives.
In scientific contexts, the term separates living bird species and their recent ancestors from earlier forms like *Archaeopteryx*.
All birds alive today—from hummingbirds to ostriches—are modern birds, sharing features like toothless beaks and fully developed flight feathers.
