The Blue-naped Parrot (Tanygnathus lucionensis), also known as the Blue-crowned Green Parrot, Luzon Parrot, and the Philippine Green Parrot, is a parrot found throughout the Philippines including islands off north and east Borneo and Talaud Islands. It is a medium size parrot (31 cm), primarily green except for a light blue rear crown and nape, pale blue lower back and rump, scalloped shoulders with orange-brown on black coverts, and blackish underwings with green underwing coverts.

It is found in secondary forests to scattered trees up to 1000m. Flock size is usually under a dozen. They feed on berries, seeds, nuts and grain. Habitat loss and trapping have made them scarce on most islands except Mindoro and Palawan. Though the Katala Foundation has raised concerns over the increasing illegal trade in this bird on Palawan.

Taxonomy

There are at least three subspecies; others have been proposed:

• T. l. lucionensis: Luzon and Mindoro
• T. l. hybridus: Polillo Islands. Blue on crown less extensive, tinged with violet. More green on wing coverts.
• T. l. talautensis (T. l. salvadorii is recognized instead by authorities on Philippine birds citing Kenneth C. Parkes' 1971 Nemouria publication): Rest of range. No blue on lower back, plumage less yellow.
