The snow partridge (Lerwa lerwa) is a gamebird in the pheasant family Phasianidae found widely distributed across the high-altitude Himalayan regions of Pakistan, China, India and Nepal. It is the only species within its genus, and is thought to be the most basal member of the "erectile clade" of the subfamily Phasianinae. The species is found in alpine pastures and open hillside above the treeline but not in as bare rocky terrain as the Himalayan snowcock and is not as wary as that species. Males and females look similar in plumage but males have a spur on their tarsus.

Rare
Under 5% of wildlife watchers report a Snow Partridge sighting in Langtang National Park on a given day, based on 16 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 172nd most-seen of the 225 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
May and July
In those months about 10% of wildlife watchers report a Snow Partridge in Langtang National Park on a given day, against under 5% in June and August–April, the lowest months. Those are among Langtang National Park's wettest months, with about 260 mm of rain a month against 10 mm in November.
Only Langtang National Park, in our data
Langtang National Park is the only park on Wallace's Line with enough records to rate Snow Partridge sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Phasianidae
The closest relatives of the Snow Partridge that you can see in Langtang National Park (family Phasianidae, Pheasants, Grouse, and Allies) are Himalayan Monal (about 30%), Kalij Pheasant (about 20%) and Common Hill Partridge (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Snow Partridge is recorded against all the birds logged in Langtang National Park (16 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.
