Some, like the red owl, have barely been seen or studied since their discovery, in contrast to the western barn owl Tyto alba, which is one of the best-known owl species in the world. However, some subspecies of the western barn owl possibly deserve to be separate species, but are very poorly known.
A long-eared owl (Asio otus) in an erect pose The laughing owl (Ninox albifacies), last seen in 1914. Genus Aegolius – the saw-whet owls, four species; Genus Asio – the eared owls, eight species; Genus Athene – two to four species (depending on whether the genera Speotyto and Heteroglaux are included or not)
The genus Asio was introduced by the French zoologist Mathurin Jacques Brisson in 1760 with the long-eared owl (Asio otus) as the type species. [1] [2] The genus name is from asiō, the Latin name used by Pliny the Younger for a type of horned owl, [3] the feather tufts on the head of these owls give the appearance of "ears" which is a defining characteristic.

In two other species of owls with asymmetrical ears, the saw-whet owl and the long-eared owl, the asymmetry is achieved by different means: in saw whets, the skull is asymmetrical; in the long-eared owl, the skin structures lying near the ear form asymmetrical entrances to the ear canals, which is achieved by a horizontal membrane. Thus, ear ...
The long-eared owl has a somewhat similar plumage to the eagle-owl, but is considerably smaller (an average female eagle-owl may be twice as long and 10 times heavier than an average long-eared owl). [25] Long-eared owls in Eurasia have vertical striping like that of the Eurasian eagle-owl, while long-eared owls in North America show a more ...
The long-eared owl is the most regularly taken as prey of any raptorial bird by Eurasian eagle-owls. Other than these two species, a large share of the raptorial prey for eagle-owls is made up of other owls. Given that all European owls are to some extent nocturnal, they may be encountered and killed upon detection by the Eurasian eagle-owl.
