Water Pipit

The water pipit is a small passerine that breeds in the mountains of southern Europe and the Palearctic eastwards to China, and is a short-distance migrant, many birds moving to lower altitudes or wet open lowlands in winter. In breeding plumage it has greyish-brown upperparts, pale pink-buff underparts, a grey head with a broad white supercilium and white outer tail feathers; in winter the upperparts are more streaked and the underparts white with light brown streaking (Wikipedia, general species account).

The song is delivered from a perch or in flight, in four or five blocks of about six repeats of a short note. It feeds mainly on small invertebrates picked off the ground or vegetation, and some plant matter. The cup nest is on the ground under vegetation or in cliff crevices, with four to six eggs laid from the end of April to early July. The account opened does not name Bhutan.
