Description
The 49 subspecies of island thrush vary dramatically in appearance, but almost all resemble a typical Turdus thrush and have a yellow bill, eye-ring and legs. The Samoan subspecies, T. p. samoensis, is identical in appearance to the blackbird (Turdus merula), whereas T. p. seebohmi of northern Borneo is dark above with a red breast and resembles the American robin (Turdus migratorius). Some subspecies have an entirely white head (including the male T. p. niveiceps, but not the female), and the Kadavu form T. p. ruficeps has an entirely orange head.

Feeding Habits
Island Thrush consumes a diverse diet including insects (especially beetles), spiders, snails, earthworms, small reptiles, carrion, fruit, and seeds, varying with local availability. It forages like blackbirds, rummaging through leaf litter and low branches, and occasionally in the canopy.
Habitat
Island Thrush inhabits varied woodlands and forests, particularly favoring environments with mature trees and an open understory. These birds are common in mountainous terrains with forest edges and clearings, ranging from lowlands to upper forest zones. They show a preference for misty montane forests in the northwestern part of their range and are adaptable to different vegetative zones, including heath and scrub. Island Thrush generally avoids densely populated avifaunal areas, choosing semi-open habitats.

Distribution Area
The island thrush is widely but patchily distributed across its range. It is present on islands in Samoa, Fiji, Vanuatu, New Caledonia, the Solomon Islands, New Guinea and surrounding islands, many Indonesian islands, the Philippines, and Taiwan. However, it is restricted to areas with bird communities of less than 25–35 species. On the larger islands (like Borneo or New Guinea) this means that it is only found at high altitudes, above 2750 m. Smaller islands can only support much smaller bird communities, and on these the island thrush may be found at lower altitudes. Two or more subspecies may exist on some islands, segregated into different habitats. The ranges of many subspecies may be as small as a single island—for example the Kadavu subspecies T. p. ruficeps.
Species Status
As a species the island thrush is not threatened and many subspecies are locally very common. However, several subspecies are threatened, and T. p. erythropleurus is considered critically so. This subspecies is found on Christmas Island, and is threatened by the introduced yellow crazy ant, which is capable of killing nestlings. Several other subspecies have declining ranges, including T. p. samoensis from Samoa, and T. p. xanthopus from New Caledonia, which is now extinct from Grande Terre and is restricted to 100 individuals surviving only on Yande and Neba. Three subspecies have become extinct: T. p. vinitinctus from Lord Howe Island, T. p. mareensis from the Loyalty Islands and the nominate race T. p. poliocephalus from Norfolk Island. T. p. poliocephalus was relatively common as recently as 1941, but by 1975 it had become extinct, due to introduced black rats, habitat loss and hybridization following colonisation by the closely related Common Blackbird.
