The crested serpent eagle (Spilornis cheela) is a medium-sized bird of prey that is found in forested habitats across tropical Asia. Within its widespread range across the Indian subcontinent, Southeast Asia and East Asia, there are considerable variations and some authorities prefer to treat several of its subspecies as completely separate species. In the past, several species including the Philippine serpent eagle (S. holospila), Andaman serpent eagle (S. elgini) and South Nicobar serpent eagle (S. klossi) were treated as subspecies of the crested serpent eagle. All members within the species complex have a large-looking head with long feathers on the back, giving them a maned and crested appearance. The face is bare and yellow joining up with the ceres while the powerful feet are unfeathered and heavily scaled. They fly over the forest canopy on broad wings and tail have wide white and black bars. They call often with a loud, piercing and familiar three or two-note call. They often feed on snakes, giving them their name and are placed along with the Circaetus snake-eagles in the subfamily Circaetinae.

Likely
About 50% of wildlife watchers report a Crested Serpent Eagle sighting in Royal Bardia National Park on a given day, based on 189 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 18th most-seen of the 233 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
In that month about 70% of wildlife watchers report a Crested Serpent Eagle in Royal Bardia National Park on a given day, against about 30% in December, the lowest month. That is one of Royal Bardia National Park's driest months, with about 30 mm of rain against 590 mm in July. August has too few records to rate.
Between 3 and 6 am
Across all the parks we cover, that three-hour window holds the most Crested Serpent Eagle sightings with a recorded time, and about half of them come between 6 pm and 6 am: it is most active around dawn and dusk.
6th of 43
Of the 43 parks where we can rate Crested Serpent Eagle sightings, Royal Bardia National Park ranks 6th at about 50%. The best odds are in Wilpattu National Park (Sri Lanka, about 70%), Kinabatangan Wildlife Sanctuary (Malaysia, about 60%) and Kaziranga National Park (India, about 60%). All parks ranked.

GBIF citizen-science records
It is estimated from how often the Crested Serpent Eagle is recorded against all the birds logged in Royal Bardia National Park (189 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.
