Likely
About 60% of wildlife watchers report a Crested Hawk-Eagle sighting in Udawalawe National Park on a given day, based on 380 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 21st most-seen of the 166 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.
March–April, June, October and December–January
In those months about 60% of wildlife watchers report a Crested Hawk-Eagle in Udawalawe National Park on a given day, against about 40% in May and July, the lowest months.

GBIF citizen-science records
It is estimated from how often the Crested Hawk-Eagle is recorded against all the birds logged in Udawalawe National Park (380 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.
