Hyacinth macaws are the world’s longest parrots. They have impressive cobalt blue feathers, which contrast with their bare yellow eye-ring (which, in other species of macaw is white). The Hyacinth macaws are native to central and eastern South America and now inhabit only three distinct areas: the Pantanal, Bolivia and Paraguay. Hyacinth macaws feed mainly on nuts from arcuri and bocaiuva palms and other native palms. Hyacinth macaw numbers are in decline due to the illegal pet trade, being highly prized as pets and habitat loss, being changed due to cattle ranching and agriculture.
