Cyanopsitta spixii, commonly known as Spix's Macaw, is a parrot native to Brazil. It features vivid blue plumage, a greyish head, and a long tail. Known for its rarity, the species inhabits the gallery forests along the Rio S?o Francisco. It is critically endangered and once presumed extinct in the wild.

Cyanopsitta spixii, commonly known as the Spix's Macaw, is native to Brazil. Historically, its range was limited to the Rio São Francisco region in the northeastern part of Brazil, particularly in the states of Bahia and Pernambuco.

The Spix's Macaw is typically found in the gallery forests along seasonal rivers, known as 'riachões,' in the semi-arid region of the Caatinga biome. This area is characterized by a hot and dry climate with sparse and seasonal rainfall. The average annual temperature ranges from 23°C to 27°C, and the vegetation mainly consists of thorny scrub and small trees.

The ecological niche of the Spix's Macaw is largely tied to the availability of Caraibeira (Tabebuia aurea) trees, which provide both nesting sites and a food source. The macaws feed on seeds, nuts, and fruits found in these habitats. This species is adapted to a highly specialized niche, relying on specific tree species and the unique environmental conditions of the Caatinga biome.
