Rare
Under 5% of wildlife watchers report a Brownish-flanked Bush-Warbler sighting in Royal Manas National Park on a given day, based on 46 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 228th most-seen of the 388 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.
March and May
In those months about 10% of wildlife watchers report a Brownish-flanked Bush-Warbler in Royal Manas National Park on a given day, against under 5% in April, June–July and October–February, the lowest months. August and September have too few records to rate.
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.
3rd of 5
Of the 5 parks where we can rate Brownish-flanked Bush-Warbler sightings, Royal Manas National Park ranks 3rd at under 5%. The best odds are in Taroko National Park (Taiwan, about 10%) and Jiuzhaigou National Park (China, about 10%).
GBIF citizen-science records
It is estimated from how often the Brownish-flanked Bush-Warbler is recorded against all the birds logged in Royal Manas National Park (46 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.
