Once common, the species has declined drastically as a result of habitat loss and illegal capture for the wild animal trade.[3] The size of the remaining wild population is unknown, but perhaps only around 50 individuals,[3] while others speculate that the lack of recent sightings might mean that it already is extinct in the wild.[4]
In an attempt at saving the species, a captive breeding program based on confiscated individuals has been initiated by the Cikananga Wildlife Center in Java (since 2011) and a few European
Appearance
Javan green magpies are primarily a vivid green, with a black "mask" marking around their eyes, russet wings, and white tertiary feathers. They have bright red beaks and eyerings; their legs are equally bright, ranging from red to orange. Their eyes are dark brown and they have a relatively short tail.
The bright green plumage is the result of a combination of structural coloration, and the yellow pigment lutein, which they gain from their insect diet.[3] They also feed on small lizards and frogs.[4]
In captivity, adults turn bluish (the structural colour of their feathers) if their diet is inadequate in lutein.[3]
