The American barn owl is a medium-sized, pale-coloured owl with long wings and a short, squarish tail. [3] 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. [4]
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.

When large numbers of small prey are readily available, barn owl populations can expand rapidly. König proposed that Tyto alba delicatula should be split off as a separate species, to be known as the eastern barn owl, which would include the subspecies T. d. sumbaensis, T. d. meeki, T. d. crassirostris and T. d. interposita.

Many owls use plucking posts for prey that has been caught on the ground. Barred owls often use old nests for the purpose. [2] Plucking posts are used by barn owls which hunt by flying low and slowly over an area of open ground, hovering over spots that conceal potential prey. The barn owl feeds primarily on small vertebrates, particularly rodents.
It has an effortless wavering flight as it quarters the ground, alert to the sounds made by potential prey. Like most owls, the barn owl flies silently; tiny serrations on the leading edges of its flight feathers and a hairlike fringe to the trailing edges help to break up the flow of air over the wings, thereby reducing turbulence and the ...
The plumage on its underbelly and wings is gleaming white, an unusual trait that in theory should make it more difficult for the owl to approach its prey undetected. Unlike the snowy owl, the barn ...
