With luck
About 10% of wildlife watchers report a Slaty-headed Parakeet sighting in Dehradun on a given day, based on 408 verified sightings from GBIF citizen-science data. It is the 78th most-seen of the 280 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.
January and February
In those months about 20% of wildlife watchers report a Slaty-headed Parakeet in Dehradun on a given day, against under 5% in May–June, August–September and November, the lowest months. Those are among Dehradun's driest months, with about 40 mm of rain a month against 370 mm in July.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Slaty-headed Parakeet sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.

GBIF citizen-science records
It is estimated from how often the Slaty-headed Parakeet is recorded against all the birds logged in Dehradun (408 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.
