Distribution and habitat
Trichoglossus haematodus is found in eastern Indonesia, on Buru, Seram, Misool, Waigeo, Numfoor, Yapen and the Aru Islands, in Indonesia and Papua New Guinea on New Guinea, in the Bismarck Archipelago, the Solomon Islands, Vanuatu and New Caledonia.
The species occupies a wide range of lowland and wooded hill habitats, including mangroves, rainforest, nypa forest, swamps, savanna and woodland. It also occupies human-modified areas including coconut plantations, gardens, agricultural land and disturbed forest. It is found from sea level up to as high as 2,440 m (8,010 ft); this upper altitude level varies by location.
Coconut lorikeets are monogamous birds, choosing only one partner for their whole life. They are diurnal birds living in very large bands. In the evening, they join their fellows in a dormitory tree. These birds may breed throughout most of year, depending on the region. Usually they breed in the spring, from July to December. They usually raise one brood a year, sometimes two.[citation needed]
Nests are usually located in holes in decaying wood, such as hollows of eucalyptus trees, at a height of 25 metres (82 ft) above the ground. Females lay two matte white, round eggs and incubate them for 23–25 days. Parents feed the chicks for 7–8 weeks, after which they leave the nest and after another 2–3 weeks they become completely independent.
