These conures have vibrant green feathers, complemented by a slightly blue upper chest and a black face. Some of their flight feathers are black, their tail tip is blue, and their leg feathers are red.

Nanday conures have a diverse diet consisting of fruits, seeds, nuts, flowers, and other parts of plants. During non-breeding seasons they display nomadic behavior and are frequently observed foraging on the ground.

As social birds, they do many things in groups, including searching for nest sites. They gather in groups, with several birds perching on the edge of a tree cavity to inspect it before one bird ventures in. If the site is approved a pair of Nanday Conures may move in, laying 3 to 5 eggs and incubating them for 24 to 26 days. They generally use a plain nesting hollow with no additional nesting material. Both parents incubate the eggs and care for the chicks until they are able to leave the nest at around 8 weeks old.  Chicks may still remain with the parents for several months as they learn survival skills.

The conservation status of Nanday Conures is currently classified as Least Concern on the IUCN Red List. These parrots are able to adapt to human disturbance of the landscape by changing their diet and nesting locations. While their population is increasing within their natural range, they face ongoing threats. Over 270,000 individuals have been captured for the pet trade since 1891.

They can live up to 45 years.
