The Lears Macaw (Anodorhynchus leari), also known as the Indigo Macaw, is a large, all blue Brazilian parrot that is a member of a large group of Neotropical parrots known as macaws. It was first described by Charles Lucien Bonaparte in 1856. The Lears Macaw is 70?75 cm. (28?30 in.) long and weighs around 950 g. (2.1 lb.). It is metallic blue with a faint, often barely visible tinge of green, and a yellow patch of skin at the base of the heavy, black bill. This macaw is rare with a highly restricted range.
