) 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''.
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.
Behaviour

s. It will also take fruit and seeds, depending on what is locally available. Its foraging technique is described as similar to that of the blackbird, investigating the leaf litter and low branches in dense cover, but in some places will also forage in the canopy.
Breeding
Most island thrushes breed in discrete two- to three-month seasons (the precise timing varies depending on location), although the birds in Fiji

Conservation
