Hodgson's Treecreeper

Hodgson's treecreeper is a small, fairly drab bird from the southern rim of the Himalayas, 12.5cm long, found in Bhutan, China, India, Myanmar, Nepal and Pakistan. It is brownish above with lighter and darker streaks and off-white below and on the supercilium. It is browner above than the common treecreeper, with a contrasting rufous rump, and has a long curved bill (Wikipedia, general species account).

It nests in tree crevices, with a typical clutch of four to six reddish-brown-blotched pinkish-white eggs. Its distinctness from the common treecreeper was recently validated. The song starts with two 'shree' calls characteristic of this species and its close relatives, then a few warbling calls, and finally two up- and down-slurred notes (Wikipedia, general species account).
