The pygmy hanging parrot, red-billed hanging parrot or green hanging parrot (Loriculus exilis) is a tiny species of parrot in the Psittaculidae family. It is endemic forest, mangrove and other wooded habitats on the Indonesian island of Sulawesi. It is threatened by habitat loss. It is overall green with a red rump and a small red chin-spot bordered by blue (the red chin-spot and blue border is reduced in the female). It occurs together with the larger great hanging parrot, but unlike that species the bill of the pygmy hanging parrot is red.
The hanging parrots are birds in the parrot genus Loriculus. This is a group of small parrots from tropical southern Asia.
These little parrots, about 13 cm (5.1 in) long, are mostly green plumaged and short-tailed. Often head coloring helps to identify individual species. These parrots are unique among birds for their ability to sleep upside down.
