Green-winged macaws are distinguished from the similar but smaller scarlet
macaw by color (scarlets are a lighter, brighter red) and the scarlet does not
have facial feather lines. The head and beak of the Green wing is much
more massive. The tail is long and tapered.
Green-winged macaws are found in Panama but their primary range is
tropical lowland forests of central South America, throughout the Amazon
Basin and south into Bolivia and Argentina. Green-winged macaws are
found in lowland humid forests, deciduous forests and lower mountain
forests where they eat primarily fruits, palm nuts and flowers, foraging
primarily in the forest canopy. They nest in cavities, especially in large soft
wood trees in which they can modify the nest cavity but also in crevices and
cliffs. Usually fly in pairs or small family groups.
