Habitat:

It is a bird of forests closed and open, including secondary growth, coconut plantations, patches of mangrove and banana to the 1.000 meters above sea level; and not so strongly linked to coastal habitats as the Great-billed Parrot. Is usually found in flocks of up to 12 individuals who sit in community and make regular flights at dawn and in the evening between the feeding and resting areas. Feeds on fruit trees.

The breeding It has been observed in the months of April to June. Registered a nest the natural cavity or abandoned Woodpecker hole, often a clear. There is no data on the size of the Sunset.

Food:

Fruits and seeds of forest trees, Palm fruit, young coconuts, the banana and papaya.

Distribution:

The population of the Blue-naped Parrot distributes lengthwise of the Philippines and Talaud Islands, (Indonesia). Specific records found in the islands of Balut, Bantavan, Basilan, Biliran, Bohol, Bongao, Cagayan Islands, Calamian Islands, Caluya, Cebu, Cuimaras, Jolo, Leyte, Luzon, Maestre de Campo, Malanipa, Manuk Manka, Marinduque, Masbate, Mindanao, Mindoro, Black, Palawan, Surigao del Sur, Polillo Islands, Romblon, Samar, Sanga Sanga, Sarangani Islands, Samal, Sibay, Sibutu, Sibuyan, Siquijor, Tables, Tawitawi, Ticao, Tumindao and Green (Philippines); Karakelong and Salibabu (Talaud).

Apparently, small groups of birds in Mantanani Kiss (Northwest Sabah), and SI-Amil (until 100 birds present in 1962) and Maratua off the northeast coast of Borneo; The existence of a wild population was also reported around Kota Kinabalu, (Sabah).

Occasional leaks occur in other parts, including the Sangir Islands.

The species was described as common in Salibabu in the Group of Talaud and 1978 (more numerous there that the Blue-backed Parrot) and they are still regularly about there and in the nearby Karakelong During observations on 1995 (Many in a last record in 1997).

In other areas the species is rare. Recent records in Philippines they come mainly from Mindoro and Palawan, places that seem to be the bastion of the species.

Distribution of subspecies:

  • Tanygnathus lucionensis lucionensis

    : The nominal.

  • Tanygnathus lucionensis hybridus

    : (Salomonsen, 1952) – Present in Polillo island, to the North of Philippines.

  • Tanygnathus lucionensis talautensis

    : (AB Meyer & Wiglesworth, 1895) – Talaud Islands (North Moluccas).

  • Tanygnathus lucionensis [salvadorii u horrisonus]:

    (Ogilvie-Grant, 1896) – Philippines, (except North), but it can be rare or extinct on many islands. Also in some small islands off Northwest and northeast of Borneo (If Amil, Mantanani), where it was possibly introduced, especially in this last island.

Conservation:

• Current red list category of the UICN: Near threatened

• Population trend: Decreasing

The total population is provisionally estimated that it could be below the 10,000 copies and 1993 (Lambert et to the. 1993).

The population is suspected may be declining due to the capture for the bird trade and the degradation of habitat expansion and forestry due to agricultural pressures.

Proposed conservation actions Palawan:

– Determine the impact of trade on the population of the species.
– Revise its estimate of the world population.
– Estimate the rates of decline based on the rates of deforestation within its range.
– Protect effectively important extensions of high forest with trees suitable to nest in key places throughout its distribution area, both in the areas of strict protection, as in areas of multiple use.

In captivity:

Fairly quiet.
Occasionally available.
