River Lapwing

The river lapwing is 29 to 32cm long and breeds from the Indian subcontinent east to Southeast Asia, including much of northern and north-eastern India, and appears to be entirely sedentary. It has a black crest, crown, face and central throat, grey-white neck sides and nape, a grey-brown breast band and white underparts with a black belly patch (Wikipedia, general species account).

The back is brown, the rump white and the tail black, and in flight it is striking, with black primaries and white underwings. The call is a sharp 'tip-tip' or 'did-did-did'. It lays two eggs in a ground scrape. The account opened does not name Bhutan, so its occurrence there is flagged for checking.
