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.

Rare
Under 5% of wildlife watchers report a Crested Serpent Eagle sighting in Tainan on a given day, based on 75 verified sightings from GBIF citizen-science data. It is the 69th most-seen of the 116 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
February and March
In those months about 10% of wildlife watchers report a Crested Serpent Eagle in Tainan on a given day, against under 5% in April to January, the lowest months. Those are among Tainan's driest months, with about 40 mm of rain a month against 440 mm in August.
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.
16th of 39
Of the 39 cities where we can rate Crested Serpent Eagle sightings, Tainan ranks 16th at under 5%. The best odds are in Kuala Lumpur (Malaysia, about 20%), Thrissur (India, about 20%) and Taipei (Taiwan, about 10%).
GBIF citizen-science records
It is estimated from how often the Crested Serpent Eagle is recorded against all the birds logged in Tainan (75 verified sightings), 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.
