Rare
Under 5% of wildlife watchers report a Common Torrent Hawk sighting in Chennai on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 338th most-seen of the 376 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
March and May–June
In those months about 10% of wildlife watchers report a Common Torrent Hawk in Chennai on a given day, against under 5% in April and July–February, the lowest months. Those are among Chennai's driest months, with about 45 mm of rain a month against 290 mm in November.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Common Torrent Hawk sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
4th of 4
Of the 4 cities where we can rate Common Torrent Hawk sightings, Chennai ranks 4th at under 5%. The best odds are in Yogyakarta (Indonesia, about 10%), Jakarta (Indonesia, about 10%) and Hyderabad (India, about 10%).
Same order: Odonata
The closest relatives of the Common Torrent Hawk that you can see in Chennai (order Odonata, Dragonflies and Damselflies) are Chalky Percher (about 40%), Wandering Midget (about 30%) and Coromandel Marsh Dart (about 30%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Common Torrent Hawk is recorded against all the insects logged in Chennai (5 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.
