Possible
About 30% of wildlife watchers report a Clamorous Reed Warbler sighting in Keoladeo National Park on a given day, based on 817 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 75th most-seen of the 278 birds we can rate there. Over three days the chance rises to about 70%, and over a week to about 90%, if each day is a fresh chance.
December to March
In those months about 40% of wildlife watchers report a Clamorous Reed Warbler in Keoladeo National Park on a given day, against about 10% in May to September, the lowest months. Those are among Keoladeo National Park's driest months, with about 15 mm of rain a month against 240 mm in July.
Between 2 and 5 am
Across all the parks we cover, that three-hour window holds the most Clamorous Reed 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.
Yes
Of the 9 parks where we can rate Clamorous Reed Warbler sightings, Keoladeo National Park has the highest daily chance: about 30%. Next come Satpura National Park (India, under 5%) and Nagarhole National Park (India, under 5%).
GBIF citizen-science records
It is estimated from how often the Clamorous Reed Warbler is recorded against all the birds logged in Keoladeo National Park (817 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.
