With luck
About 10% of wildlife watchers report an Indian Grey Hornbill sighting in Nagpur on a given day, based on 223 verified sightings from GBIF citizen-science data. It is the 52nd most-seen of the 196 birds 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.
January–April and September
In those months about 20% of wildlife watchers report an Indian Grey Hornbill in Nagpur on a given day, against about 10% in May–August and October–December, the lowest months. Those are among Nagpur's driest months, with about 45 mm of rain a month against 310 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.
25th of 44
Of the 44 cities where we can rate Indian Grey Hornbill sightings, Nagpur ranks 25th at about 10%. The best odds are in Indore (India, about 60%), Bareilly (India, about 60%) and Dehradun (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 Nagpur (223 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.
