Possible
About 20% of wildlife watchers report a Little Blue Marsh Hawk sighting in Kolkata on a given day, based on 52 verified sightings from GBIF citizen-science data. It is the 54th most-seen of the 213 insects we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
June to August
In those months about 30% of wildlife watchers report a Little Blue Marsh Hawk in Kolkata on a given day, against under 5% in April and November–February, the lowest months. Those are among Kolkata's wettest months, with about 290 mm of rain a month against 10 mm in December.

GBIF citizen-science records
It is estimated from how often the Little Blue Marsh Hawk is recorded against all the insects logged in Kolkata (52 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.
