Kuhl's lorikeet: where and when to see them

Kuhl's lorikeet is a brightly colored Pacific parrot with green upperparts, a red underside and a blue-violet crown. Its surviving distribution reflects both island history and conservation transfers, rather than a continuous range across Polynesia. Rimatara is especially important to its survival. Introduced predators, particularly rats, can threaten island populations, so strict biosecurity is as relevant to this small flower-feeding bird as protection of its wooded habitat.

These lorikeets move rapidly among flowering trees, often calling conspicuously during flight. Pairs and small groups inspect blossoms, clamber along branches and sometimes hang awkwardly while feeding. Their movements follow changing food availability rather than a predictable daily visitor timetable. Nesting takes place in tree cavities, making suitable old trees valuable. Although colorful, feeding birds can disappear surprisingly well within sunlit foliage, where brief calls or falling flower fragments may reveal them. Courtship displays involve pairs preening each other and sharing food items. They are known to form communal roosts in dense foliage outside of the breeding season.

• The tongue has brushlike structures that help collect nectar and pollen.
• The Rimatara population became a source for a conservation reintroduction to Atiu.
• Traditional protection on Rimatara helped the lorikeet survive when it vanished from other islands.
• Its distribution has been influenced by human transport between Pacific islands.

There is no simple archipelago-wide viewing season because the bird occurs on only particular islands and follows local flowering. The broadly cooler, drier months can suit walking on Rimatara, but weather patterns vary across Polynesia and do not define a universal breeding season. Breeding activity on Rimatara has been observed from August to December, coinciding with local resource abundance. The timing of local flowering peaks often correlates with periods of increased activity and visibility.

They use wooded island landscapes, including coconut groves, gardens, mixed tree cover and areas retaining native flowering plants. A mosaic of feeding trees and nesting cavities is important. Their restricted island occurrence means apparently suitable tropical vegetation elsewhere may hold none. They are particularly reliant on native trees such as `Erythrina variegata` and `Ficus prolixa` which provide both food and nesting sites. Historical introductions to other islands, like Hawaii, have not resulted in self-sustaining populations.

Nectar and pollen are major foods, collected with a specialized brush-tipped tongue. Soft fruits and small invertebrates supplement flower resources. Feeding opportunities vary as different trees bloom, encouraging movement between gardens, groves and remnant woodland within occupied islands. They consume a wide variety of flower nectar, including that from coconut palms, `Hibiscus tiliaceus`, and `Calophyllum inophyllum`. Their diet is crucial for pollinating native flowering plants within their limited range.

Identification

Its red underparts, green back and blue-violet crown separate it from the predominantly blue blue lorikeet and the differently patterned ultramarine lorikeet. Juveniles are similar to adults but have a duller, sometimes brownish crown and an orange rather than red bill. They measure about 19 cm in length and have a relatively short, wedge-shaped tail.
