With luck
About 10% of wildlife watchers report a Clamorous Reed Warbler sighting in Chennai on a given day, based on 523 verified sightings from GBIF citizen-science data. It is the 78th most-seen of the 223 birds we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
May–June and December–March
In those months about 10% of wildlife watchers report a Clamorous Reed Warbler in Chennai on a given day, against under 5% in April and July–November, the lowest months. Those are among Chennai's driest months, with about 50 mm of rain a month against 290 mm in November.

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.
22nd of 56
Of the 56 cities where we can rate Clamorous Reed Warbler sightings, Chennai ranks 22nd at about 10%. The best odds are in Vasai-Virar (India, about 40%), Makassar (Indonesia, about 30%) and Cairo (Egypt, about 20%).
GBIF citizen-science records
It is estimated from how often the Clamorous Reed Warbler is recorded against all the birds logged in Chennai (523 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.
