Description

The Madagascar Serpent-eagle is a medium-sized raptor with a long rounded tail and short rounded wings.cite encyclopedia| title =Madagascar Serpent Eagle | encyclopedia =The Official World Wildlife Fund Guide to Extinct Species of Modern Times| volume =1| pages =13-14| publisher =Beacham Publishing | date =1997] It is dark grey on its back and a lighter grey on its belly, breast, and throat. Dark barring covers the bird's body. It has yellow eyes and a sharp, hooked beak with strong talons.

Distribution and habitat

This bird inhabits dense, humid, and broadleafed evergreen forests in northeastern and east-central Madagascar. It rarely ventures above 550 meters (1800 ft).

Ecology and behavior

This serpent-eagle is diurnal. It eats snakes, lizards, and frogs, which they hunt from high perches, swooping down from it perch and grasping its prey in its talons when it spots it.

Conservation

This species was believed to be extinct, with the last confirmed sighting being from 1950. However, sightings in 1977 and 1988 led to hope for the species' rediscovery. It was rediscovered in 1993 by the Peregrine Fund.

This species is threatened by the destruction of its specialized habitat and a presumed low rate of reproduction.

Etymology

The prefix "eu-" is Greek for "good". "Triorchis" is a Latinization (Pliny the Elder) of Greek "triorkhis" (τριορχης), which Aristotle and Theophrastus used for a kind of hawk, possibly the Common Buzzard. The Greek word means "having three testicles".
