[2] Owls hunt mostly small mammals, insects, and other birds, although a few species specialize in hunting fish. They are found in all regions of the Earth except the polar ice caps and some remote islands.

Eurasian eagle-owl in Poland. Most owls are nocturnal or crepuscular birds of prey. Because they hunt at night, they must rely on non-visual senses. Experiments by Roger Payne [1] have shown that owls are sensitive to the sounds made by their prey, not the heat or the smell. In fact, the sound cues are both necessary and sufficient for ...
The lack of a deep facial disc in fish owls is another indication of the unimportance of sound relative to vision in these owls, as facial disc depth (as well as inner ear size) are directly related to how important sound is to an owl's hunting behavior. Similar adaptations, such as unwillingness to submerge beyond their legs and lack of sound ...
Much like the related, continental short-eared owls, pueo primarily consume small mammals, which they can expertly detect from far distances with their large eyes, an adaptation for superb night vision and hunting after-dark. Their incredibly advanced nocturnal vision also enables them to fly through densely wooded areas with ease, deftly ...
The fairly powerful talons of a tawny owl. The tawny owl (Strix aluco) is an opportunistic and generalized predator.Peak hunting activity tends to occur largely between dusk to midnight, with owls often following an erratic hunting pattern, perhaps to sites where previous hunts were successful.
U.S. officials are considering issuing hunting permits to help limit the West Coast population of invasive barred owls.
The northern hawk-owl is a partially diurnal hunter, although it has been recorded hunting at varying times and does not appear to have a preferred hunting time. [11] Whether the bird resides in Eurasia or North America, the strategy is usually similar. The northern hawk-owl will perch and scour the immediate area for prey. [16]
