Tytonidae & Strigidae

Tytonidae and Strigidae are two families of owls. Tytonidae is represented here by the barn owl (tyto alba) and the boreal owl (aegolius funereus) from Belarus. 

Last month went i've been to London, ive visited the natural History Museum and that was where bought the barn owl card. The other card was sent by Irina.

The Barn Owl (Tyto alba) is the most widely distributed species of owl, and one of the most widespread of all birds. T. alba is found almost anywhere in the world except polar and desert regions, Asia north of the Alpide belt, most of Indonesia, and the Pacific islands.

Ghostly pale and strictly nocturnal, Barn Owls are silent predators of the night world. Lanky, with a whitish face, chest, and belly, and buffy upperparts, this owl roosts in hidden, quiet places during the day. By night, they hunt on buoyant wingbeats in open fields and meadows. You can find them by listening for their eerie, raspy calls, quite unlike the hoots of other owls. Despite a worldwide distribution, Barn Owls are declining in parts of their range due to habitat loss. Barn Owls nest and roost in cavities, abandoned barns and other buildings, and dense trees. At night, Barn Owls hunt by flying low, back and forth over open habitats, searching for small rodents primarily by sound.Barn Owls require large areas of open land over which to hunt. This can either be marsh, grasslands, or mixed agricultural fields. For nesting and roosting, they prefer quiet cavities, either in trees or man-made structures such as barns or silos. - in: http://www.allaboutbirds.org/guide/barn_owl/id

The Boreal Owl (Aegolius funereus) is a small unsociable nocturnal owl. 

The Boreal Owl breeds in dense coniferous forests across northern North America and Eurasia, and in mountain ranges such as the Alps and the Rockies. It lays 3–6 eggs in a tree hole. Across much of Europe, and to a lesser extent in Asia and North America, naturalists and biologists put up nest boxes for these and other small owls. 

These Owls can live for at least 7-8 years.
