The Paleocene genera Berruornis and Ogygoptynx show that owls were already present as a distinct lineage some 60–57 million years ago (Mya), hence, possibly also some 5 million years earlier, at the extinction of the non-avian dinosaurs. This makes them one of the oldest known groups of non-Galloanserae landbirds.

How do owls change over time?

Adult owls lose their feathers and grow new ones every year. But each owl stays the same color throughout its life. The colors of an owl’s feathers help it blend in with the natural environment and, of course, keep it warm. Snowy Owls have white feathers that help them hide in their snowy habitat.

What is the history of owls?

In early Indian folklore, Owls represent wisdom and helpfulness, and have powers of prophecy. This theme recurs in Aesop’s fables and in Greek myths and beliefs. By the Middle Ages in Europe, the Owl had become the associate of witches and the inhabitant of dark, lonely and profane places, a foolish but feared spectre.
