Welcome to the Opus, an interactive, multimedia encyclopaedia that anyone can edit. You can use the Opus to find out about everything to do with birds - from the birds themselves to the places you can find them.
Identification
Medium large raptor about 50–74 cm (19¾-29 in) in length.
Adult
Dark brown upperparts and head
Hooded appearance at rest
Pale brown underparts and underwing coverts
Appears large-headed and owl-like due to face s hape and position of eyes
Tail and flight feathers black with broad white stripes
Distribution
Southern Asia
- Widespread and generally common from northern India, south to Sri Lanka, east to southern China, Hainan, Taiwan and the southern Ryukyu Islands. South to the Andaman Islands and Malay Peninsula.
- Also breeds on Palawan, Borneo, Sumatra, Java and many smaller islands.
Taxonomy
Taxonomy confused and confusing in the face of little research and multiple distinct forms.
Subspecies abbotti may be elevated as "Simeulue Serpent-eagle", S. abbotti, sipora as "Mentawai Serpent-eagle", S. sipora, asturinus as "Nias Serpent-eagle", S. asturinus, baweanus as "Bawean Serpent-eagle", S. baweanus and (sometimes) natunensis as "Natuna Serpent-eagle", S. natunensis
Clements recognizes 21 subspecies
Habitat
Forest and forest edge, riverine woodland, farmland and sometimes near villages. Occurs up to 3,000m in the Himalayas.
Breeding
A large stick nest is constructed in the middle of a tall tree. The clutch consists of 1, occasionally two, eggs. These are incubated by the female for about 35 days, with the male helping to feed them once they are hatched. They leave the nest when they are about 2 months old.
If you're looking for a particular bird, place, or anything else related to the birding world, try searching for it using the search box at the top, or to the left, of this page. You can also get an overview of all the birds, bird song, locations or other wildlife by using the tabs above.
