Javan Green Magpie

Overview

The Javan green magpie (Cissa thalassina) is a passerine bird in the crow family, Corvidae, endemic to montane forests on the island of Western Java, Indonesia. This critically endangered species was once more widespread, but it has suffered significant population declines due to habitat loss and illegal capture for the wild animal trade.
Once common, it is now found in only four protected areas, with estimates of the remaining wild population being as low as 50 individuals. While others speculate that the lack of recent sightings might mean that it already is extinct in the wild.
