The females have an average mass between 270–407 g (9.5–14.4 oz), and the males between 279–390 g (9.8–13.8 oz). The average body length is 327–384 mm (12.9–15.1 in) for females and 355–403 mm (14.0–15.9 in) for males, making it the smallest of the grouse species.

With luck
About 10% of wildlife watchers report a Severtzov's Grouse sighting in Jiuzhaigou National Park on a given day, based on 8 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 108th most-seen of the 131 birds we can rate there. Over three days the chance rises to about 20%, and over a week to about 30%, if each day is a fresh chance.
April to June
In those months about 10% of wildlife watchers report a Severtzov's Grouse in Jiuzhaigou National Park on a given day, against under 5% in July to December, the lowest months. Those are among Jiuzhaigou National Park's wettest months, with about 140 mm of rain a month against 15 mm in December. January to March have too few records to rate.
Only Jiuzhaigou National Park, in our data
Jiuzhaigou National Park is the only park on Wallace's Line with enough records to rate Severtzov's Grouse sightings: about 10% of wildlife watchers there report one on a given day.

GBIF citizen-science records
It is estimated from how often the Severtzov's Grouse is recorded against all the birds logged in Jiuzhaigou National Park (8 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.
