The blue-winged macaw occurs in eastern and southern Brazil (with a remnant population north-east), eastern Paraguay and, at least formerly, in far north-eastern Argentina and east of Bolivia. It occurs in evergreen and deciduous forests, with a preference for gallery forest. They mainly feed on seeds of "Cnidoscolus phyllacanthus", "Jatropha", "Guazuma ulmifolia", and the non-native "Melia azedarach". However, the birds also feed on fruits and nuts.
