行为
The lorikeets are hard to spot in dense foliage. They are generally found in small groups or flocks. They are known to travel between the inland foliage and coastal palms to feed on coconuts.<p>The diet of the birds is composed of nectar, pollen, fruits, and butterfly and moth larvae. The majority of nectar eaten by the lorikeets comes from the flowers of Scaevola sericea and Timonius polygamus.<p>Their breeding season is thought to be around April or the start of May.<p>The lorikeets are assessed as vulnerable by the IUCN. They are thought to have a stable population of 720-1820 individuals. Due to their extremely limited range, the main threat to the survival of the lorikeets is the accidental introduction of predators to Henderson Island and habitat loss due to deforestation or natural disasters. They, however, seem to have adjusted to the introduction of at least one invasive predator, the Polynesian rat. There has been an unsuccessful attempt to eradicate invasive rodents from Henderson Island.

Found in a wide variety of savanna habitats, from moist broadleaf woodland to dry thorn savanna. Also found in villages, towns, and cultivated areas.
