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. This 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.
It has three subspecies, from west to east: Certhia hodgsoni hodgsoni Brooks, 1871 – N Pakistan to NW India Certhia hodgsoni mandellii Brooks, 1874 – Nepal, Bhutan, NE India Certhia hodgsoni khamensis Bianchi, 1903, Kham... Wikipedia →

With luck
About 10% of wildlife watchers report a Hodgson's Treecreeper sighting in Langtang National Park on a given day, based on 33 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 112th most-seen of the 225 birds we can rate there. Over three days the chance rises to about 20%, and over a week to about 50%, if each day is a fresh chance.
February–June and August–December
In those months about 10% of wildlife watchers report a Hodgson's Treecreeper in Langtang National Park on a given day, against under 5% in January and July, the lowest months.
Between 3 and 6 am
Across all the parks we cover, that three-hour window holds the most Hodgson's Treecreeper sightings with a recorded time, and about half of them come between 6 am and 6 pm: it is most active around dawn and dusk.
2nd of 2
Of the 2 parks where we can rate Hodgson's Treecreeper sightings, Langtang National Park ranks 2nd at about 10%. The best odds are in Jiuzhaigou National Park (China, about 20%).
GBIF citizen-science records
It is estimated from how often the Hodgson's Treecreeper is recorded against all the birds logged in Langtang National Park (33 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
