These very rare and endangered macaws live in seasonally flooded grasslands where there are dry islands of trees. It feeds and nests in motacú palms (Attalea princeps) and buriti palms (Mauritia flexuosa). It is duller in colour than the Blue-and-gold macaw, which is heavier and tends to push the Blue-throated macaw out from nesting sites. Here it is feeding on genipapo fruit which is used by the indigenous people to make body paint.
