Great Nicobar Serpent Eagle

The Great Nicobar serpent eagle, also called the South Nicobar serpent eagle, is probably the smallest known eagle, weighing about 450 g, with a wingspan of 85–95 cm and a body length of about 38–42 cm. It is endemic to forest on the Indian island of Great Nicobar and is threatened by habitat loss (Wikipedia, general species account).

All major authorities now treat it as a species, though in the past it was sometimes considered a subspecies of the Central Nicobar serpent eagle, which is itself treated as either a subspecies of the crested serpent eagle or a separate species. The cached account gives no diet or breeding information. SoIB 2023 rates it a Moderate conservation priority, an island endemic with a Restricted range of only about 1,400 km² (Wikipedia, general species account; SoIB 2023).
