The Spix's Macaws are endemic to interior and northeastern Brazil, where populations of them occurred in southern Piaui (Parnaguá) and north-east Bahia (Juazeiro). They may also have been found in extreme southern Maranhao (Sick and Teixera 1979), western Pernambuco, and northeastern Goias (Ridgely 1981). Local movements are likely in response to environmental conditions or food availability.
They were known to be mostly sedentary within their range, with some movements in response to rainfalls, availability of food and favored nesting or roosting sites. All, or most, of their daily activities (foraging, nesting, etc.) were otherwise performed within a limited range. However, outside the breeding season they would sometimes leave their home range for up to several weeks - but nobody really knew where they were at the time.
They typically remain close to Caraibeira trees that they use for nesting and roosting. Their dependence on this tree species greatly restricts their natural range in which they occur locally and irregularly.
They were rarely observed in groups larger than two or three; however, it is possible that they traveled in flocks of up to fifteen birds before their numbers were so radically diminished
