The barn owl, although also by nature a cavity nester, does not generally acclimate to well-wooded areas where the tawny owl is at home. [107] Both the long-eared and barn owls prefer voles where they are available, especially as both often hunt in open areas where they are common, whereas Apodemus mice tend to be slightly preferred by tawny owls.
The European owls with the most similar diets to eagle-owls are 475 g (1.047 lb) tawny (Strix aluco) and 785 g (1.731 lb) Ural owls (Strix uralensis), although both are considerably smaller and less powerful and more specialized to hunt in wooded environments.
Tawny and brown fish owls are both slightly smaller than co-occurring Eurasian eagle-owls, and Blakiston's fish owls are similar or slightly larger than co-occurring large northern eagle-owls. Fish owls, being tied to the edges of fresh water, where they hunt mainly fish and crabs, also have slightly differing, and more narrow, habitat preferences.
Compared to other owls of similar size, the barn owl has a much higher metabolic rate, requiring relatively more food. Relative to its size, barn owls consume more rodents. Studies have shown that an individual barn owl may eat one or more voles (or their equivalent) per night, equivalent to about fourteen percent of the bird's bodyweight.
Arizona has 13 species of owl, including great horned owls, barn owls and screech owls. Here's where they live and what to do if you encounter one.
The snowy owl (Bubo scandiacus), [4] also known as the polar owl, the white owl and the Arctic owl, [5] is a large, white owl of the true owl family. [6] Snowy owls are native to the Arctic regions of both North America and the Palearctic, breeding mostly on the tundra. [2]
Only this species and, more infrequently, other fairly large owls from the genus Strix are known to "snow-plunge" for prey, a habit that is thought to require superb hearing not possessed by all types of owls. [12] Unlike the more versatile eagle and horned owls, great grey owls rely almost fully upon small rodents. What species they eat ...
