Appendix II
Threat Summary:
Has a restricted range. Possibly now extinct on Negros and Siquijor, and very rare on Mindoro, Luzon and other islands due to a combination of habitat loss and heavy illegal trapping. The reported scarcity of birds in markets suggests the genuine rarity of the species. Mining activities are reducing habitats across Tawi-Tawi.
Range:
T.s. everetti: Central to southern Philippine Islands.
T.s. burbidgii: Sulu Archipelago, southern Philippine Islands.
T.s. duponti: Luzon, northern Philippine Islands.
T.s. freeri: Polillo, northern Philippine Islands.
Habitat:
Thought to be similar to Azure-rumped Parrot: tropical, lowland, and montane forests, as well as mangrove swamps and degraded forests.
Wild Diet:
Thought to be similar to Azure-rumped Parrot: may include fruits of Leptospermum and Ficus, nuts, seeds and berries and occasionally cultivated crops.
Ecology and Behaviour:
Very little known of ecology but thought to be similar to Azure-rumped Parrot: Resident, quiet and inconspicuous. Mostly encountered singly, in pairs or less often in small flocks.
Clutch and Egg Size:
Likely 2-3 eggs.
Breeding Season:
Possibly April. Nest is likely in tree hollow.
