Blue-naped Parrot, also known as the Luzon Parrot or Philippine Green Parrot


Blue-naped Parrot

The Blue-naped Parrot, Tanygnathus lucionensisis - also known as the Luzon Parrot or Philippine Green Parrot - is endemic to the Philippines and Maluku Islands (formerly known as Moluccan Islands).

Its preferred habit includes secondary forest areas up to 1000m. Habitat loss and trapping have made this parrot scarce on most islands except Mindoro and Palawan. They usually can be seen in small groups up to a dozen.


Description:

This medium-sized parrot averages 12.4 inches or 31 cm in length. The plumage is primarily green except for a light blue rear crown and nape (back of the neck). It has a pale blue lower back and rump, scalloped shoulders with orange-brown on black coverts, and blackish underwings with green underwing coverts.


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

  • Blue-naped Parrots - T. l. lucionensis: Luzon and Mindoro

  • Salomonsen's Blue-naped Parrots - T. l. hybridus: Polillo Islands. Blue on crown less extensive, tinged with violet. More green on wing coverts.

  • Talaud / Talautese Blue-naped Parrots - T. l. talautensis: Rest of range. No blue on lower back, plumage less yellow.
