Although frequently speculated to be extinct (there have been no definite reports since the 1960s), BirdLife International maintains this macaw in the Critically Endangered category, given convincing reports by local people that the bird remains extant, and because not all of its former range has been subjected to adequate surveys. One of a quartet of blue macaws, all of which have declined dramatically as a result of illegal trapping and, in some cases, habitat destruction, the Glaucous Macaw is pale turquoise-blue with a large grayish head, a proportionately long tail and a massive bill, with yellow patches around the eyes and bill base. It was widespread but clearly very locally distributed in northern Argentina, southern Paraguay, northeast Uruguay and southern Brazil, but only two 20th-century reports exist. Some recent commentators have suggested that the allopatric Lear’s Macaw (Anodorhynchus leari) and the present species should be considered conspecifics.
