Olive-headed Lorikeet

Identification

The olive-headed lorikeet is a compact parrot measuring approximately 24 cm (9.5 inches) in length. Its most distinctive feature is its olive-coloured head, which contrasts sharply with a bright green collar encircling the neck. The rest of the plumage is predominantly green. The bird's striking facial features include an orange-red beak, red irises, and grey legs. Males and females are identical in external appearance, making field identification based on plumage alone impossible. Juveniles are slightly greener on the head, with brown beaks and brown irises, providing a useful distinction from adults in the field.

Range & Habitat

The olive-headed lorikeet is endemic to Indonesia's Lesser Sundas islands, giving it a highly restricted range. It is found on Timor and smaller nearby islands, including the medium to large volcanic islands of Adonara and Lembata, located off the eastern tip of Flores in East Nusa Tenggara. This limited distribution makes it a speciality species for dedicated birders.

The species shows a strong preference for forested environments. It inhabits primary montane forests, secondary growth, and savanna woodland, typically at elevations between roughly 1000 and 2300 metres. It also occurs in rainforests and closed canopy forests, though it can be found in cultivated areas as well.

Behaviour & Diet

Lorikeets in general are known for their aggressive temperament, and the olive-headed lorikeet is no exception. These birds are extremely aggressive toward individuals of their own species and toward other species, both in wild and captive settings. Aggression intensifies around food sources, perches, and nest sites. In hostile encounters, they perform elaborate visual threat displays typical of the genus Trichoglossus.

Vocally, the olive-headed lorikeet is highly vocal and quite noisy. Its calls are repetitive, long, and wheezy, interspersed with rapid, buzzy trilling notes and muted sequences of harsh squeaks, twitters, and whistles. The primary vocalizations are sharp, high-pitched sounds expressed as "kreet!" or "kurrk," supplemented by softer, lisping "tsleet!" calls and various muted, grating tones. In the wild, the species feeds on pollen, nectar, fruits, seeds, and insects and their larvae.

Best Time & Places to See It

Travellers seeking the olive-headed lorikeet should head to the Lesser Sundas islands of Indonesia, particularly Timor and the nearby volcanic islands of Adonara and Lembata. Focus your search in primary montane forests, secondary growth, and closed canopy forests at elevations between 1000 and 2300 metres. The breeding season runs from November to February, which may be a productive time to locate birds as they are more active and vocal during this period, though birds can be encountered year-round within their restricted range.

Photography Tips

The olive-headed lorikeet's small size and preference for closed canopy forests present challenges for photographers. Early morning visits to fruiting trees or flowering plants will increase your chances of productive encounters, as the birds feed on nectar and fruit. The bird's vibrant green plumage and contrasting olive head and orange-red beak provide excellent colour contrast for photography. Be prepared for the birds' aggressive and highly vocal behaviour—their loud, distinctive calls will alert you to their presence even when visibility is limited. Given the species' restricted range and forest habitat, patience and multiple visits to suitable locations will be necessary for obtaining satisfactory photographs.
