The nanday parakeet (Aratinga nenday) also known as the black-hooded parakeet or nanday conure is a medium-small mostly green Neotropical parrot.
The nanday parakeet is 32–37 cm (13–15 in) long, weighs 140 g (4.9 oz), 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.
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.
Nanday parakeets usually find holes in trees to nest in. It lays three or four eggs. After raising its young, all birds will form rather large communal roosts until the next breeding season.
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 24 × 24 × 30 inches (60 × 60 × 75 cm) 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 six hours a day. While they will accept most parrot seed mixes, seed-only diets are nutritionally inadequate, reduce their lifespan considerably and may cause them to become underweight. Pellet-based diets with fruits and vegetables offered daily are much preferable. 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.
