Members of the parrot genus Psittacula or Afro-Asian ring-necked parrots, as they are commonly known in aviculture, originate from Africa to South-East Asia. It is a widespread group with a clear concentration of species in south Asia, but also with representatives in Africa and the islands of the Indian Ocean. This is the only genus of parrot which has the majority of its species in continental Asia. Of all the extant species only Psittacula calthropae, Psittacula caniceps and Psittacula echo do not have a representative subspecies in any part of mainland continental Asia. The rose-ringed parakeet, Psittacula krameri, is one of the most widely distributed of all parrots.

The red-breasted parakeet is a parrot native to Southeast Asia. It is among the more widespread species of the genus and is the species which has the most geographical variations. It is easily identified by the large red patch on its breast. An alternative name is the moustached parakeet depending on subspecies. Most of the subspecies are confined to minuscule islands or a cluster of islands in Indonesia. One subspecies occurs in the Andaman islands, and one subspecies occurs in continental Southeast Asia and partly extending to northeastern parts of South Asia along the foothills of the Himalayas. Some of the island races may be threatened by the wild bird trade. The nominate race, which occurs in Java, is close to extinction.
