With luck
About 10% of wildlife watchers report a Clamorous Reed Warbler sighting in Kolkata on a given day, based on 871 verified sightings from GBIF citizen-science data. It is the 65th most-seen of the 247 birds we can rate there. Over three days the chance rises to about 20%, and over a week to about 50%, if each day is a fresh chance.
November to January
In those months about 20% of wildlife watchers report a Clamorous Reed Warbler in Kolkata on a given day, against under 5% in April to September, the lowest months. Those are among Kolkata's driest months, with about 15 mm of rain a month against 330 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.
16th of 56
Of the 56 cities where we can rate Clamorous Reed Warbler sightings, Kolkata ranks 16th 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 Kolkata (871 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.
