With luck
About 10% of wildlife watchers report an Oriental Darter sighting in Satpura National Park on a given day, based on 82 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 121st most-seen of the 259 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.

In that month about 20% of wildlife watchers report an Oriental Darter in Satpura National Park on a given day, against under 5% in June and August–October, the lowest months. That is one of Satpura National Park's driest months, with about 15 mm of rain against 690 mm in July.
Between 3 and 6 am
Across all the parks we cover, that three-hour window holds the most Oriental Darter sightings with a recorded time, and about 6 in 10 of them come between 6 am and 6 pm: it is most active around dawn and dusk.
16th of 29

GBIF citizen-science records
It is estimated from how often the Oriental Darter is recorded against all the birds logged in Satpura National Park (82 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.
