Madagascar Serpent-Eagle

The Madagascar serpent eagle is a medium-sized raptor with a long rounded tail and short rounded wings. 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. It measures 57 to 66 cm (22 to 26 in) long with a wingspan of 90 to 110 cm (35 to 43 in).

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

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

The prefix eu- is Greek for "good","well","true", and "pleasant". Tri Orchis is a Latinization (Pliny the Elder) of Greek triórkhēs (τριόρχης), which Aristotle and Theophrastus used for a kind of hawk, possibly the common buzzard. The Greek word means "having three testicles". This erroneous bit of anatomy has been connected with the ease of mistaking a bird's adrenal gland for a testicle. Astur is Latin for a kind of hawk.
