I have included here some of the more unusual parrots found in captive collections.

Hawkheaded Parrot ( Deroptyus  accipitrinus)                                                                                    There are two known subspecies of this mid sized South American parrot. The most commonly found nominate race is found north of the Amazon, west through Guianas and southern  Venezuela to south-est Columbia. The other subspecie D.a.fuscifrons lives from South of the Amazon in Brazil, as far south as northern Mato Grosso.This subspecie has a darker head and brown rather than white forehead.

They are unique in that they are able to raise a fan of feathers around the neck, during play or as a sign of aggression.They are successfully bred in captivity in small numbers. Said to do best in sheltered isolated fights. They are very active parrakeet like birds. Often English bred Hawkheads can be quite fearless to the keeper.

As pets they can be a little unpredictable sometimes having a tendency to be quite nippy.

Purple-bellied Parrot (Triclaria malachitacea)                                                                                  A parrot found in southeast Brazil and north to south Bahia. Mountain parrot of the costal areas. The adults are dimorphic with the male having the destinctivepurple belly. Immatures do not normally have the purple coloured belly.Noe regarded as very endangered in the wild. In aviculture known as a quiet parrot with a melodic call similar to a thrush.

Occasionally seen in collections where they are known as active flying parrots given spacious aviary's. Breeding not thought to be difficult.

Slender-billed Conure (Enicognathus leptorhynchus)                                                                              This is a large conure of Central and southern Chile, with the very destinctive elongated upper mandible. Seen in large flocks outside the breeding season. Their slender bill is used for excavating grass roots and wild seed shoots. They often nest in colonoies in cliffs. They have been imported in the past but not often seen so much these days. In captivity will often spend much time digging about on the aviary floor. Found to be quite easy to breed, but quite noisy. 

Kea (Nestor notabilis)                                                                                                                             A parrot of the mountains of South Island of New Zealand. Living up in the mountain forest and sub-alpine scrubland. Very inquisitive and active parrot. Unafraid of human interaction in the wild and aften congregates around popular parking and camping sites. Unfortunately has a reputation for causing vandalism to vehicles parked .Persecuted as sheep pedators, but it is most likely that they only scavange the carcases of dead sheep. In captive collections can be kept on a colony basis where successful breeding is often achieved.

Persquet's Parrot (Psittrichas fulgidus)                                                                                                  A unusal parrot found in New Guinea this unique parrot is dimorhic in that the cock and hen appear to be the same apart from a small arear of red colouration behind the eyes of the adult cock which is not seen in the hens. Another mountain parrot, now rarely found because of hunting for food and the feathers by the local inhabitants. Been found to be very difficult to acclimatise in European climates. Not often found in captive collections. Feeds on figs, fruit and lory foods.Breeding  success rare.

Great-billed Parrot (Tanygnathus megalorhynchus)                                                                         There are 8 subspecies recognised of this rarely seen parrot. They are parrots of the Islands of the Northern and central Mollucas, Indonesia and Islands off the Philippines. Although many were imported during the 80's few remain today in Europe. So it appears that these parrots have not been found to be so hardy. They are regarded as quiet but very active parrots in spacious aviary's. And have been kept on a colony basis.

Black-lored Parrot (Tanygnathus gramineus)                                                                        Found on the Buru Island and Indonesia. Now regarded as rare in the wild, similar in nature to the Great-billed parrots, but hardly ever seen in captive collections. The one in the photo was seen at Loro Parque.
