New Caledonian barn owl Tyto letocarti, extinct, from the island of New Caledonia in Melanesia Index of animals with the same common name This page is an index of articles on animal species (or higher taxonomic groups) with the same common name ( vernacular name).
The American barn owl is a medium-sized, pale-coloured owl with long wings and a short, squarish tail. However, the largest-bodied race of barn owl, T. f. furcata from Cuba and Jamaica, is also an island race, albeit being found on more sizeable islands with larger prey and few larger owls competing for dietary resources.

The barn owl is relatively common throughout most of its range and not considered globally threatened. If considered as a single global species, the barn owl is the second most widely distributed of all raptors, after only the peregrine falcon. It is wider-ranging than the also somewhat cosmopolitan osprey.
The eastern barn owl is native to southeastern Asia and Australasia. The eastern barn owl is nocturnal over most of its range, but in some Pacific islands, it also hunts by day. They specialise in hunting animals on the ground, and nearly all of their food consists of small mammals which they locate by sound, their hearing being very acute.
Barn owl in flight. The barn owl is a medium-sized, pale-coloured owl with long wings and a short, squarish tail. There is considerable size variation across the subspecies, with a typical specimen measuring about 33 to 39 cm (13 to 15 in) in overall length, with a wingspan of some 80 to 95 cm (31 to 37 in).
Before and after social pairing and mating occurs, bird song is mainly dedicated to territorial defense. This behavior is a sexually selected trait because it ensures defense of the female who is rearing her offspring. [9] There is also some evidence that vocal amplitude effects male-male competition in such species as the great tit. Most ...
Another species from the same genus, the meadow vole, has promiscuously mating males, and scientists have changed adult male meadow voles' behavior to resemble that of prairie voles in experiments in which a viral vector was used to increase a single gene's expression within a particular brain region.
