Systematics History

Editor’s Note: This article requires further editing work to merge existing content into the appropriate Subspecies sections. Please bear with us while this update takes place.

Possibly forms a species pair with T. megalorynchos. Additional proposed races paraguenuskoikeimoronigrorum and siquijorensis are included within Salvadori. Five subspecies were recognized.

Subspecies

Feral population (presumably race salvadorii) around Kota Kinabalu, W Sabah, in N Borneo.

Distribution

Editor’s Note: Additional distribution information for this taxon can be found in the ‘Subspecies’ article above. In the future, we will develop a range-wide distribution article.

Habitat

Lowland forest up to 1000 m, secondary forest, and scattered trees within agricultural lands close to the forest; also mangroves, coconut groves, and banana patches. Although present on large islands, this bird appears to be a small island specialist adapted to survival in relatively confined wooded areas.

Movement

No information. Populations confined to small islands must be highly sedentary, but regular dispersal from such sites also seems likely.

Diet and Foraging

Fruits and seeds of forest trees, palm fruit, young coconuts, bananas, and papaya.

Sounds and Vocal Behavior

Flight call a grating “krreh…krreh…krreh…”. When perched, vocabulary includes several nasal screeches and squawks combined with more piercing or squeaky screeches.

Breeding

Apr-Jun. Nest in a natural cavity or in the deserted hole of a large woodpecker, often in a clearing. No information on clutch size, but the size of eggs laid in captivity 36–40·9 mm × 25–28·4 mm

 

Conservation Status

Not globally threatened. Currently considered Near Threatened, and previously, Endangered. CITES II. Possibly now extinct on Negros and Siquijor, and very rare on Mindoro, Luzon, and other islands, owing to a combination of habitat loss and high levels of illegal trade for both domestic and international markets; it is clearly uncommon on Sibuyan. However, the number of small islands on which it survives is not known and may in fact be very considerable. It was very common on larger islands in the Sulu Archipelago in 1971. It survives on Palawan albeit under great trapping pressure, and remains common in Talaud Is, although judged uncommon on Salebabu in 1985, but regular there and on Karakelong in 1995. It occurs in some national parks in the Philippines, e.g. Bataan National Park, Quezon National Park, and Minalungaw National Park, Luzon, and is fairly common in St Paul’s Subterranean National Park, Palawan.
