Hodgson's treecreeper (Certhia hodgsoni ) is a small passerine bird from the southern rim of the Himalayas. Its specific distinctness from the common treecreeper (C. familiaris ) was recently validated.

H
starts withThis is a small bird, 12.5 cm (4.9 in) long, of fairly drab appearance. It is brownish with lighter and darker streaks above, and off-white below and on the supercilium. It is browner above than the common treecreeper (C. familiaris ), with a contrasting rufous rump. It has a long curved bill and long stiff tail feathers.
The song starts with two of the shree calls characteristic for this species and its close relatives. Then follow one or a few warbling calls, and finally (usually) two up- and downslurring notes. Each sound is about 0.3 seconds long, and the whole song takes about 2 to 2.5 seconds. It drops in pitch at a constant rate from around 7.5 kHz initially to 6 kHz, slurring down to 4 kHz once or twice in the end.
Hodgson's treecreeper is found in the countries of Bhutan, China, India, Myanmar, Nepal and Pakistan. It inhabits temperate to cool tropical montane forests. Mostly resident in coniferous woodlands, it may move downhill to oak/rhododendron woodlands in winter. However, in Bhutan for example C. h. mandellii is not uncommon all year round in moist Bhutan fir (Abies densa ) forests between approximately 3,000 and 4,000 meters ASL. The stiff tail feathers enable the bird to creep up vertical tree trunks looking for arthropod prey. It nests in tree crevices, and 4–6 reddish-brown blotched pinkish-white eggs are the typical clutch size.
Although the stretched-out range of this rather sedentary species is prone to habitat fragmentation in the long run, C. hodgsoni is just as common as its northern relatives. The IUCN therefore considers it a Species of least concern.
