A prehistoric relative, Nandayus vorohuensis, was described from Late Pliocene fossils found in Argentina.
Description
The Nanday Parakeet is 32–37 cm in length, and is mostly green in color. Its most distinguishing characteristic, for which it is named, is its black facial mask and beak. It also shows black trailing flight feathers on its wings and has a long tail edged at the end in blue. The upper chest is bluish-green and the lower chest is a paler green. Feathers covering the thighs are red.
Behaviour
Food and feeding
The bird feeds on seeds, fruit, palm nuts, berries, flowers and buds. Feral birds will also come to bird feeders. Wild birds primarily use scrub forest and forest clearings around settlements. It frequents open savannah, pastures and stockyards in South America where it is considered a pest in some areas.
Breeding
Nanday Parakeets usually find holes in trees to nest in. It lays 3-4 eggs. After raising its young, all birds will form rather large communal roosts until the next breeding season.
Aviculture
In captivity they make wonderful pets if cared for and socialized properly. They all have distinct personalities and appreciate toys. They require a cage or enclosure that is a minimum of 24x24x30 inches as they are inclined to climb, flap their wings and have long tail feathers. They also like to be outside of their cage at least two hours a day. They will accept most parrot seed mixes or (preferably)pellet-based diets with fruit and vegetables daily. This can be accomplished by giving them a raisins, apple slices, or other fruit or vegetable daily. These birds are extremely intelligent and skilled escape artists. Some of them will talk, others will not, depending on their personality. They are noted for having a very loud call and are not suited for apartments.
Fearing the birds may escape and become feral agricultural pests, the state of Tennessee, USA bans the keeping of Nanday Parakeets as well as Monk Parakeets.
