Madagascar Serpent-eagle
Eutriorchis astur
Justification This species has recently been found in several new locations, extending its known range considerably. In addition, the use of playback techniques has demonstrated that the species is not as rare as previously thought. For these reasons the species has been downlisted to Endangered. However its habitat is increasingly reduced and fragmented by deforestation, resulting in a continuing decline in its very small population.

This species was believed to be extinct, with the last confirmed sighting being from 1950.[2] However, sightings in 1977 and 1988 led to hope for the species' rediscovery.[2] 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.
