Rare
Under 5% of wildlife watchers report a Yellowish-bellied Bush-Warbler sighting in Chengdu on a given day, based on 8 verified sightings from GBIF citizen-science data. It is the 141st most-seen of the 156 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 Yellowish-bellied Bush-Warbler in Chengdu on a given day, so our monthly data shows no clear season.
Between 3 and 6 am
Across all the parks we cover, that three-hour window holds the most Yellowish-bellied Bush-Warbler sightings with a recorded time, and about 6 in 10 of them come between 6 pm and 6 am: it is most active around dawn and dusk.
Only Chengdu, in our data
Chengdu is the only city on Wallace's Line with enough records to rate Yellowish-bellied 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 Yellowish-bellied Bush-Warbler is recorded against all the birds logged in Chengdu (8 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.
