Northern Wheatear

The northern wheatear is larger than a European robin, 14.5–16 centimetres long, with a wingspan of 26–32 centimetres and a weight of 17–30 grams. Both sexes show a white rump and tail with a black inverted T at the tip. The summer male has grey upperparts, a buff throat, and black wings and face mask; in autumn he resembles the female apart from the black wings. The female is pale brown above and buff below. The song is whistling and crackly, and the call a chat-chack. (Wikipedia, general species account)

This migratory insect-eater is the most widespread wheatear in Europe and North and Central Asia, breeding in open stony country. It makes one of the longest journeys of any small bird, and all birds winter largely in Africa, including some that breed in northern Asia. Birds first breed at one year old. The female builds the nest alone in a cavity such as a rabbit burrow, rock crevice or wall, while the male sings nearby; clutches are four to seven eggs. (Wikipedia, general species account)
