Likely
About 40% of wildlife watchers report a Brownish-flanked Bush-Warbler sighting in Hangzhou on a given day, based on 594 verified sightings from GBIF citizen-science data. It is the 19th most-seen of the 219 birds we can rate there. Over three days the chance rises to about 70%, and over a week to over 90%, if each day is a fresh chance.
May and June
In those months about 60% of wildlife watchers report a Brownish-flanked Bush-Warbler in Hangzhou on a given day, against about 20% in August and October–November, the lowest months. Those are among Hangzhou's wettest months, with about 190 mm of rain a month against 65 mm in December.
Between 1 and 4 pm
Across all the parks we cover, that three-hour window holds the most Brownish-flanked Bush-Warbler sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
2nd of 19
Of the 19 cities where we can rate Brownish-flanked Bush-Warbler sightings, Hangzhou ranks 2nd at about 40%. The best odds are in Guiyang (China, about 50%).
GBIF citizen-science records
It is estimated from how often the Brownish-flanked Bush-Warbler is recorded against all the birds logged in Hangzhou (594 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.
