The species were first inhabited Tabebuia aurea which is a woodland place in Brazil. They had a very restricted habitat. They stayed in the trees here for nesting, feeding and roosting, their primary food was seeds and nuts from the trees in Tabebuia aurea. However, due to deforestation, the numbers of these macaw’s declined around the 20th Century.

The International Union for Conservation of Nature (IUCN) classified these species as extinct in wild, but some of them are kept in captives and several breeding programs were undertaken and are now maintained through a captive breeding program at several conservation organizations under the aegis of the Brazilian government.

However, Brazilian Chico Mendes Institute for Biodiversity Conservation (ICMBio) is now planning to take these birds in the wild once again when there are sufficient birds in captive.

Spix Macaw’s reach sexual maturity at 7 years of age. Mating involves a lot of courtship rituals like feeding each other, flying together staying together, etc. They make holes in large Caraibeira trees and they reuse the nests made here year after year.

The breeding season for Spix is around November to March, and they lay eggs around January, this is due to the environmental factor in the Caraibeira region. On average, a Spix can lay around 3-4 eggs and the incubation period of these eggs is around 25-28days with only females performing incubation duties.

Spix’s can stay for around 20 years on an average. Their diet in particular is seeds and nuts of various trees such as Joazeiro, Baraúna, Imburana, Facheiro, Phoradendron species, Caraibeira, Angico, Umbu and Unha-de-gato.

The Spix Macaw has now being held in captive as there are no sightings of the wild in nature. As of census during 2013, there are around 96 of these parrots held in captive and are present in Qatar, Germany, Spain, and Brazil.
