The habitat where it breeds in Costa Rica is practically non-seasonal, evergreen rainforest, with rain some ten months of the year, a precipitation of 1,500 to 3,500 mm a year, and an average temperature of 27 °C throughout the year. In Costa Rica the habitats where great green macaws occur during breeding season is dominated by the almendro (Dipteryx oleifera) and Pentaclethra macroloba, with secondarily raffia palms (Raphia spp.)
