About These Birds
Bermuda Saw-whet Owl
The Bermuda Saw-whet Owl was a small owl endemic to Bermuda that became extinct in the 17th century. It is known only from fossil bones and was likely a colonist from the North American Saw-whet Owl that evolved in island isolation. Its extinction was driven by human settlement, habitat clearance, and introduced predators.
