Blue lorikeet  (Vini peruviana)

Classified as Vulnerable (VU) on the IUCN Red List (1), and listed on Appendix II of CITES (3).

This stout lorikeet is immediately identifiable by its striking pattern of white cheeks and bib against a mostly dark blue plumage, combined with an orange bill and legs (2) (4). No less recognisable is this bird’s call, which consists of a very high-pitched hissing screech scheee-scheee (4).

The blue lorikeet is today found on only 9 of up to 24 islands on which it was known to occur at the time of European discovery of the Pacific. Eight of these islands are located in French Polynesia, including the Society Islands and the northern atolls of the Tuamotu Archipelago (5). An additional population occurs on Aitutaki, in the Cook Islands (4). Recent surveys in French Polynesia, combined with information from previous surveys, suggest a global population estimate for the species of between 7,200 and 9,000 individuals (5)

The blue lorikeet is most commonly found on atolls and low islands where it is typically found in coconut plantations (5). On high islands it is found in all habitats, but is most common in lowland woodlands, mixed stands of native and cultivated trees, flowering plants, gardens, and coconut and banana plantations (2) (4).

Breeding has been recorded in October, December and January, with nests found high up in holes in trees. Clutches of two eggs are incubated for 25 days in captivity, and the nestling period lasts around 60 days (2).

The blue lorikeet feeds on nectar, soft fruit, flowers and leaf shoots, particularly of coconut, banana, guava and mango (2) (4). It is also observed to consume small insects and the larvae (caterpillars) of moths and butterflies (5).

The extinction of blue lorikeets from many islands is primarily a result of predation by black rats (Rattus rattus) (6) and feral cats introduced by humans, as well as hunting for illegal trade, mainly by locals (4) (6). A particularly violent hurricane is also thought to have had a significant impact on bird populations on Makatea, in the Tuamotus (4).

Survival of this species is dependent on the absence of black rats on the islands where it remains. Thus, raising conservation awareness about the need to prevent the introduction of this animal is essential in the long-term protection of this colourful lorikeet (2). In addition, eradication of black rats on infested islands should be undertaken (5).
