Likely
About 60% of wildlife watchers report an Indian Grey Hornbill sighting in Dehradun on a given day, based on 3,750 verified sightings from GBIF citizen-science data. It is the 7th most-seen of the 280 birds we can rate there. Over three days the chance rises to about 90%, and over a week to over 90%, if each day is a fresh chance.
February
In that month about 70% of wildlife watchers report an Indian Grey Hornbill in Dehradun on a given day, against about 40% in May, the lowest month. That is one of Dehradun's driest months, with about 45 mm of rain against 370 mm in July.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Indian Grey Hornbill sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 44 cities where we can rate Indian Grey Hornbill sightings, Dehradun ranks 3rd at about 60%, level with the leaders once rounded. The best odds are in Indore (India, about 60%) and Bareilly (India, about 60%).
GBIF citizen-science records
It is estimated from how often the Indian Grey Hornbill is recorded against all the birds logged in Dehradun (3,750 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.
