The blue-naped parrot (Tanygnathus lucionensis), also known as the blue-crowned green parrot, Luzon parrot, the Philippine green parrot, and locally known as pikoy, is a parrot found throughout the Philippines.
This 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.
Distribution and ecology
The species is widespread throughout the Philippines, including the Talaud Islands and islands off north and east Borneo (with introduced population in Borneo itself, e.g. Kota Kinabalu). It is found in secondary forest, at forest edges and in plantations at elevations of up to 1000 m. Flock size is usually under a dozen. The blue-naped parrot feeds on mangoes, berries, seeds, nuts and grains. It nests in tree holes.
Habitat loss and trapping have has made this species scarce on most islands except Mindoro and Palawan. The Katala Foundation has raised concerns over the increasing illegal trade of this bird on Palawan.
There are currently five recognized subspecies. Others are now generally considered invalid.
- 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. salvadorii: Rest of Philippines.
- T. l. horrisonus: Maratua.
- T. l. talautensis: Talaud.
