The snowy owl is in many ways a very unique owl and differs from other species of owl in its ecological niche. [7] [146] Only one other owl, the short-eared owl, is known to breed in the High Arctic. [7] However, the snowy owl shares its primary prey, the brown and collared lemmings, with a number of other avian
The snowy owl has effective snow camouflage. The coloration of the owl's plumage plays a key role in its ability to sit still and blend into the environment, making it nearly invisible to prey. Owls tend to mimic the coloration and sometimes the texture patterns of their surroundings, the barn owl being an exception.
The barred owl is a powerful vocalist, with an array of calls that are considered "spectacular, loud and emphatic". [42] Calls probably carry well over 0.8 km (0.50 mi). [43] Its usual call is a series of eight accented hoots ok-ok-ok-ok ok-ok-buhooh, or the "typical two-phrase hoot" with a downward pitch at the end.

The main characteristic of the barn owls is the heart-shaped facial disc, formed by stiff feathers which serve to amplify and locate the source of sounds when hunting. [19] Further adaptations in the wing feathers eliminate sound caused by flying, aiding both the hearing of the owl listening for hidden prey and keeping the prey unaware of the owl.
The northern saw-whet owl makes a repeated tooting whistle sound. Some say they sound like a saw being sharpened on a whetstone. [21] These calls are usually produced by males searching for mates, so they can be heard more often beginning in January and continuing through the end of the breeding season in early July. [22]
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 localization of mice from a distant ...
