Crested Serpent Eagle (Spilornis cheela)
Spilornis is a genus of bird of prey in the Accipitridae family. As adults all have dark crowns, and bright yellow eyes and cere. These medium-sized raptors are found in forests of southern Asia and are known as serpent-eagles; an English name shared with two African species from the genera Dryotriorchis and Eutriorchis.
As traditionally defined, there are 6 species in this genus, but several small island populations that usually are included in the crested serpent eagle have been proposed split into separate species.
