Adonara and Lembata are medium to large volcanic islands located off the eastern tip of Flores, in East Nusa Tenggara (Lesser Sundas), Indonesia.

The olive-headed lorikeet performs elaborate ranges of visual threat displays during hostile interactions, like other parrots of the genus Trichoglossus.

[6] It is said that calls are repetitive, long and wheezy; also rapid, buzzy trilling notes and muted series of harsh, longer squeaks, twitters and whistles.

[7] They primarily produce sharp, high-pitched sounds expressed as “kreet!” or “kurrk,” but also emits a softer, lisping “tsleet!” along with various muted, grating tones.

Other fruit and vegetable options include carrots, fresh corn on the cob, frozen sweetcorn, Swiss chard, lettuce, dandelion, sowthistle, and chickweed, dried figs soaked in water for a few hours, spray millet, a small amount of soaked or sprouted sunflower seed, and/or oats.

[5] When it was sold, a Rainbow Lorikeet (Trichoglossus haematodus moluccanus) was said to be 32 years old and still reproducing, but no further information was available on the bird.
