Hanging parrots are birds in the genus Loriculus, a group of small parrots from tropical southern Asia.
About 13 cm (5.1 in) long, hanging parrots are mostly green plumaged and short-tailed. Often head coloring helps to identify individual species.[1] They are unique among birds for their ability to sleep upside down.[2]
