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.

Possible
About 30% of wildlife watchers report a Crested Serpent Eagle sighting in Keoladeo National Park on a given day, based on 632 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 95th most-seen of the 278 birds we can rate there. Over three days the chance rises to about 60%, and over a week to about 90%, if each day is a fresh chance.
January
In that month about 50% of wildlife watchers report a Crested Serpent Eagle in Keoladeo National Park on a given day, against under 5% in June–July and September, the lowest months. That is one of Keoladeo National Park's driest months, with about 30 mm of rain against 240 mm in July.
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.
22nd of 43
Of the 43 parks where we can rate Crested Serpent Eagle sightings, Keoladeo National Park ranks 22nd at about 30%.

GBIF citizen-science records
It is estimated from how often the Crested Serpent Eagle is recorded against all the birds logged in Keoladeo National Park (632 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.
