Besra

The besra, or besra sparrowhawk, is a medium-sized hawk, 29 to 36cm long, with short broad wings and a long tail. Adult males are dark blue-grey above with reddish-brown barred underparts; females are larger and browner above, and young birds dark brown above and barred brown below. It hunts by surprise, striking from a hidden perch, with a flap-flap-glide flight (Wikipedia, general species account).

It lives in dense forest, moving into more open woodland, savannah and farmland in winter, and eats lizards, dragonflies, small birds and small mammals. It nests in trees, building a new nest each year, with two to five eggs. It is widespread across southern Asia from the Indian subcontinent east to East Asia and has ten subspecies; Temminck described it in 1822 from Java. The source does not name Nepal (Wikipedia, general species account).
