Description and taxonomy
With a total length of approximately 15 cm, it is a small parrot, but the largest species of hanging parrot. It has traditionally been considered monotypic, but recent work has re-validated the subspecies croconotus from Muna and Buton Island, and quadricolor from the Togian Islands, leaving the nominate for the population on Sulawesi itself. The plumage of the nominate is overall green with an indistinct yellowish tinge to the mantle, and a red chin, leading edge of the wing, rump and crown (the red crown is missing in females). Compared to this, L. s. croconotus has slightly paler wings and tail, and a relatively distinct yellowish tinge to the mantle, while L. s. quadricolor has a clear orange-yellow patch on the mantle, a smaller red chin-spot, and a slightly brighter red rump.
