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 Dehradun on a given day, based on 39 verified sightings from GBIF citizen-science data. It is the 189th most-seen of the 280 birds we can rate there. Over three days the chance rises to under 5%, and over a week to about 10%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Chestnut-crowned Bush-Warbler in Dehradun on a given day, so our monthly data shows no clear season.
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 Dehradun, in our data
Dehradun is the only city 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.
GBIF citizen-science records
It is estimated from how often the Chestnut-crowned Bush-Warbler is recorded against all the birds logged in Dehradun (39 verified sightings), 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.
