Spotted Flycatcher

The spotted flycatcher is a small, slim Old World flycatcher about 14.5 cm long and weighing 14–20 g. It breeds in most of Europe and across the Palearctic to Siberia and winters in Africa and south-western Asia, and it is declining in parts of its range. The source does not describe its status in China. (Wikipedia, general species account)

It is an undistinguished grey-brown bird above and whitish below, with a streaked crown and breast, short black legs and a broad, pointed bill typical of aerial insectivores. It hunts from conspicuous perches, making sallies after flying insects and often returning to the same perch. It builds an open nest in a recess, often against a wall, and lays 4–6 eggs. The call is a thin, drawn-out, high-pitched tssssseeeeeppppp. (Wikipedia, general species account)
