Of the 12 parks where we can rate Indian Grey Hornbill sightings, Keoladeo National Park ranks 4th at about 50%. The best odds are in Bandhavgarh National Park (India, about 70%), Satpura National Park (India, about 50%) and Kanha National Park (India, about 50%). All parks ranked.
GBIF citizen-science records
It is estimated from how often the Indian Grey Hornbill is recorded against all the birds logged in Keoladeo National Park (1,249 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.
