|Common Name||Little blue macaw|
Extinct in the Wild
Spix's macaw is easy to identify being the only small blue macaw and also by the bare grey facial skin of its lores and eyerings. It is about 56 cm (22 in) long including tail length of 26–38 cm (10–15 in). It has a wing length of 24.7–30.0 cm (9.7–11.8 in). The external appearance of adult male and female are identical; however, the average weight of captive males is about 318 g (11.2 oz) and captive females average about 288 g (10.2 oz). Its plumage is grey-blue on the head, pale blue on the underparts, and vivid blue on the upperparts, wings and tail. The legs and feet are brownish-black. In adults the bare facial skin is grey, the beak is entirely dark grey, and the irises are yellow. Juveniles are similar to adults, but they have pale grey bare facial skin, brown irises, and a white stripe along the top-center of their beaks (along the culmen).
In the wild, the most common seeds and nuts consumed by Spix's were from Pinhão (Jatropha pohliana var. mollissima) and Favela (Cnidoscolus phyllacanthus). However these trees are colonizers, not native to the bird's habitat, so they could not have been historical staples of the diet.

- The mating call of the Spix's macaw can be described as the sound "whichaka".
- The last known Spix's macaw in the wild disappeared in 2000.
