Note the characteristic roughened skin on their bare yellow faces. This fairly common Macaw specializes in the fruit of Mauritia palms and nest in dead palm tree cavities as seen here. It is a unique species in its own monotypic genus. Its scientific name was formerly spelled Ara manilata for gender agreement, but has been successfully argued that manilatus is a noun rather than an adjective and thus the original spelling stands (David & Gosselin, 2002).
