Tawny owl description
The tawny owl (Strix aluco) is the most common and widespread British owl (3). It is most often heard than seen; it produces a variety of vocalisations, including the familiar 'ke-wick' contact calls (6). It has a compact body and a large rounded head, and varies in colour from greyish to reddish brown with black and white streaks (2). The sexes are similar in appearance (2).Top
Tawny owl biology
Tawny owls feed mainly on small mammals such as voles, as well as insects. They occupy a favourite perch, dropping onto prey that passes by; inedible remains such as fur and bones in the form of 'owl pellets' gather below these perches (3).
Pairs begin to form territories in the autumn; this involves much hooting and calling, and males occasionally clap their wings together in a form of display (3). Nesting usually takes place in holes in hollow trees, although abandoned crow nests may be used (3). In March or early April, between two and four white eggs are laid. These are incubated by the female for up to 30 days. The male takes charge of feeding the young, who fledge after 32 to 37 days (3).Top
