Egg incubation is the process by which an egg, of oviparous (egg-laying) animals, develops an embryo within the egg, after the egg's formation and ovipositional release. Egg incubation is done under favorable environmental conditions, possibly by brooding and hatching the egg.
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.

Three species that are sometimes considered to be a single species known as barn owl or common barn owl: Western barn owl Tyto alba, from Europe, Africa, and the Middle East; American barn owl Tyto furcata, from the Americas; Eastern barn owl Tyto javanica, from southeast Asia and Australasia; Andaman masked owl Tyto deroepstorffi endemic to ...
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 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).
Crepuscular animal activity is affected by human activity, because humans are diurnal. Crepuscular animals are less likely to participate in typical foraging or reproductive behaviors and deal with increased stress and mortality rates when humans are present. [11] Animals may change their usual activity patterns in
Eggs are laid at two-day intervals and incubation begins after laying of the first egg. Eggs vary in size in synch with their ultimate body size, ranging from an average of 36.3 mm × 30.2 mm ( 1 + 7 ⁄ 16 in × 1 + 3 ⁄ 16 in) in the Northern Rockies to 33.9 mm × 29.2 mm ( 1 + 5 ⁄ 16 in × 1 + 1 ⁄ 8 in) in south Texas.

It is part of the family Strigidae, the true owl family, which contains 90% of all owl species. The other 10% of owls are part of the family Tytonidae, the barn owl family. [citation needed] The Japanese scops-owl is part of the genus Otus which is the largest genus of owls. [3] This genus includes 59 species of scops-owls found throughout Afro ...
