Its head lacks tufts common in other owls and has a paler facial disk, [25] with a white supercilium (eyebrow) and dark brown ear coverts and cheeks. The brown feathers of the upper forehead, above the supercilium, and sides of the neck have yellow-brown highlights. The feathers of the lores, chin and throat are white with black shafts. The ...
Feathers become abraded over time and all birds need to replace them at intervals. Barn owls are particularly dependent on their ability to fly quietly and manoeuvre efficiently. In temperate areas, the owls undergo a prolonged moult that lasts through three phases over a period of two years. The female starts to moult while incubating the eggs ...
A great horned owl with wet feathers, waiting out a rainstorm. The disadvantage of such feather adaptations for barn owls is that their feathers are not waterproof. [24] The adaptations mean that barn owls do not use the uropygial gland, informally the "preen" or "oil" gland, as most birds do, to spread oils across their plumage through ...
Typical owls are small to large solitary nocturnal birds of prey. They have large forward-facing eyes and ears, a hawk-like beak, and a conspicuous circle of feathers around each eye called a facial disk.

Bird ear tufts are skin projections covered in feathers found in some bird species, most notably various species of owl, vaguely resembling mammalian ears, but unrelated to the animal's hearing. Theories about their function range from improved ability to camouflage, [ 2 ] aiding in finding a suitable mate, [ 3 ] [ 4 ] to giving a more ...
Feathers are moulted gradually between June and December. [9] This species is sexually dimorphic; the female is much larger than the male, 5% longer and more than 25% heavier. [10] The tawny owl flies with long glides on rounded wings, less undulating and with fewer wingbeats than other Eurasian owls, and typically at a greater height.
