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.
In the stated study, the tawny owls would kill and eat amphibians and fish, while the long-eared owls would rarely kill and never eat these types of prey. [36] In a study of five European biomes , with about 45 prey species per biome, the tawny owl was estimated to have tied for the second most prey species per biome after the Eurasian eagle ...
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.
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.
Owls are divided into two families: the true (or typical) owl family, Strigidae, and the barn owl and bay owl family, Tytonidae. [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.
Compared to other owls of similar size, the barn owl has a much higher metabolic rate, requiring relatively more food. Weight for weight, barn owls consume more rodents—often regarded as pests by humans—than possibly any other creature. This makes the barn owl one of the most economically valuable wildlife animals for agriculture.
Yes, even you, night owls. ... The National Institutes of Health study found that 71% fewer children developed peanut allergies if they were fed products made from the nut between infancy and age ...
Unlike the more versatile eagle and horned owls, great grey owls rely almost fully upon small rodents. What species they eat depends on which small mammals are most abundant and available. In northern Canada and other parts of Scandinavia, they eat lemmings primarily. In dry parts of California's Sierra Nevada they eat mostly pocket gophers.
