Tawny owl

543:, and as with other owls, the tawny owl's two ear openings differ in structure and are asymmetrically placed to improve directional hearing. A passage through the skull links the eardrums, and small differences in the time of arrival of a sound at each ear enables its source to be pinpointed. The left ear opening is higher on the head than the larger right ear and tilts downward, improving sensitivity to sounds from below. Both ear openings are hidden under the facial disk feathers, which are structurally specialized to be transparent to sound, and are supported by a movable fold of skin (the pre-aural flap). 390: 1187: 1160: 49: 1050:
discovered and "mobbed" by small birds during the day, but they normally ignore the disturbance. Tawny owls are very territorial, and will indicate the location of their chosen territory by their vocalisations, which occur at their greatest frequency during the night, though some owls will continue to call during the day. The owl's home range is determined in early autumn, and the territory is defended throughout the winter and into spring when the breeding season begins.

The tawny owl's hearing is ten times better than a human's, and it can hunt using this sense alone in the dark of a woodland on an overcast night, but the patter of raindrops makes it difficult to detect faint sounds, and prolonged wet weather can lead to starvation if the owl cannot hunt effectively. 398: 647: 90: 1215: 2530: 912: 1297: 406: 990:. Although tawny owls occur in urban environments, especially those with natural forests and wooded habitat patches, they are less likely to occur at sites with high noise levels at night. The tawny owl is mainly a lowland bird in the colder parts of its range, but breeds to 550 metres (1,800 ft) in Scotland, 1,600 m (5,200 ft) in the 1146:, was an important cause of mortality in newly fledged young, with 36% dying between fledging and independence. The mortality risk increased with fledging date from 14% in April to more than 58% in June, and increasing predation of late broods may be an important selective agent for early breeding in this species. 591:
