Likely
About 40% of wildlife watchers report a Crested Hawk-Eagle sighting in Royal Bardia National Park on a given day, based on 153 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 35th most-seen of the 233 birds we can rate there. Over three days the chance rises to about 80%, and over a week to over 90%, if each day is a fresh chance.
October
In that month about 50% of wildlife watchers report a Crested Hawk-Eagle in Royal Bardia National Park on a given day, against about 30% in February, April and June–July, the lowest months. That is one of Royal Bardia National Park's driest months, with about 80 mm of rain against 590 mm in July. August has too few records to rate.
Between 4 and 7 am
Across all the parks we cover, that three-hour window holds the most Crested Hawk-Eagle sightings with a recorded time, and about half of them come between 6 am and 6 pm: it is most active around dawn and dusk.
5th of 34
Of the 34 parks where we can rate Crested Hawk-Eagle sightings, Royal Bardia National Park ranks 5th at about 40%. The best odds are in Udawalawe National Park (Sri Lanka, about 60%), Yala National Park (Sri Lanka, about 50%) and Wilpattu National Park (Sri Lanka, about 50%). All parks ranked.
Same family: Accipitridae
The closest relatives of the Crested Hawk-Eagle that you can see in Royal Bardia National Park (family Accipitridae, Hawks, Eagles, and Kites) are Crested Serpent Eagle (about 50%), Oriental Honey-buzzard (about 30%) and Gray-headed Fish-Eagle (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Crested Hawk-Eagle is recorded against all the birds logged in Royal Bardia National Park (153 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.
