Description

Ebird describes this bird as "A rare medium-sized parrot of lowland and foothill forest on Luzon. The two central tail feathers have extended shafts ending in a racket shape. Overall green in color, slightly darker on the back, with paler head and underparts and a pale bill. Male is more yellowish-green in color.

. Improve protection measures against logging at Subic Bay Forest Reserve. Clamp down on illegal logging within the species's range, and ensure that environmental impact assessments are carried out before any new logging concessions are granted. Establish a captive breeding population to support future reintroduction and supplementation efforts. Lobby against proposed developments that threaten suitable habitat.
