The chestnut-crowned bush warbler (Cettia major) is a species of warbler found in South Asia. Although overall population size has not been quantified, this is one of the species that is declining due to habitat destruction. Although its population trend is observed to be decreasing, its decline is not happening in rapid fashion. For this reason, this is evaluated as least concern species.
The phylogenetic relationships among the Cettia species are shown below, based on the data by the Cornell Lab of Ornithology. It split from the Chestnut-headed tesia about 5 million years ago. Wikipedia →

Rare
Under 5% of wildlife watchers report a Chestnut-crowned Bush-Warbler sighting in Jiuzhaigou National Park on a given day, based on 5 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 122nd most-seen of the 131 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.
June
In that month about 10% of wildlife watchers report a Chestnut-crowned Bush-Warbler in Jiuzhaigou National Park on a given day, against under 5% in April–May and July–December, the lowest months. That is one of Jiuzhaigou National Park's wettest months, with about 160 mm of rain against 15 mm in December. January to March have too few records to rate.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Chestnut-crowned Bush-Warbler sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Jiuzhaigou National Park, in our data
Jiuzhaigou National Park is the only park on Wallace's Line with enough records to rate Chestnut-crowned Bush-Warbler sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Cettiidae
The closest relatives of the Chestnut-crowned Bush-Warbler that you can see in Jiuzhaigou National Park (family Cettiidae, Bush Warblers and Allies) are Yellowish-bellied Bush-Warbler (about 20%) and Brownish-flanked Bush-Warbler (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Chestnut-crowned Bush-Warbler is recorded against all the birds logged in Jiuzhaigou National Park (5 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.
