Eurasian eagle-owls are subject to frequent mobbing by crows – the owl in this photograph is being pursued by a group of carrion crows (Corvus corone). The Eurasian eagle-owl rarely assumes the so-called "tall-thin position", which is when an owl adopts an upright stance with plumage closely compressed and may stand tightly beside a tree trunk.
Among the latter, the great horned owl (Bubo virginianus), in the Americas, and the Eurasian eagle-owl (B. bubo) are noted predators of barn owls. Despite some sources claiming that there is little evidence of predation by great horned owls, one study from Washington found that 10.9% of the local great horned owl's diet was made up of barn owls.
The American (North and South America) horned owls and the Old World eagle-owls make up the genus Bubo, at least as traditionally described. The genus name Bubo is Latin for owl . Its name in Russian филин ( Russian for 'filin') is one of the few native Russian words containing the letter Ф .
Genetic testing indicates that the lesser horned owl, and then the snowy owl, not the Eurasian eagle-owl, are the most closely related living species. [ 14 ] [ 12 ] Pleistocene era fossils have been found of Bubo owls in North America, which may either be distinct species or paleosubspecies , from as far east as Georgia , but predominantly in ...
The throat is white. The iris is yellow (whereas the Eurasian eagle-owl typically has an orange iris). The Eurasian eagle-owl and Blakiston's fish owl both occur in the Russian Far East and are potentially could compete for resources, although no scientifically observed interactions of any kind have been reported between these two largest owl ...
The Eurasian eagle-owl (B. bubo) is a noted predator of Western barn owl. In Africa, the principle predators of Western barn owls are Verreaux's eagle-owls and Cape eagle-owls. [33] [34] In Europe, although less dangerous than the eagle owl, the chief diurnal predators are the northern goshawk (Accipiter gentilis) and the common buzzard (Buteo ...
A Eurasian eagle owl at the Minnesota Zoo escaped its handler, only to land in a tiger enclosure, where it was killed, according to a government report and the zoo.
In North America, great horned owls (Bubo virginianus), yet another type of eagle-owl in all but name, have a squarish head and more widely separated ear-tufts. Like other Bubo species, great horned owls are also perceptibly larger and more massively built than any long-eared owl (despite being smaller than the Eurasian eagle-owl). Great horned ...
