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.
Eurasian Eagle-Owl
The Eurasian eagle-owl is one of the largest owl species in the world, with females sometimes reaching a wingspan of nearly two meters. Its deep booming call can be heard up to four kilometers away on calm nights. These apex predators sit at the top of the avian food chain, preying on other raptors including buzzards and smaller owls.
