'' and '' Syagrus coronata''). While blue macaws have been known from taxidermic and captive specimens since at least 1790, location of the Lear's macaw's endemic habitat wasn't known until 1978. The glaucous macaw was extirpated in the 1800s by clearance for agriculture and cattle grazing of the yatay palm (Butia yatay) groves upon which it fed, though rumors of its continued existence persist. Lear's macaws have made a comeback from near extinction in the early 1980s (about 60 birds) to over 1000 as a result of conservation programs. Hyacinth macaws remain locally common within parts of their range, but their range has become fragmented into three known distinct populations in southern Brazil, eastern Bolivia and northeastern Paraguay; populations are declining due to extensive trapping for the pet trade as well as habitat loss.

The genus, ''Anodorhynchus'' Spix, 1824 is one of six genera of Central and South American macaws in tribe ''Arini'' of macaws, parakeets and closely related genera. The macaws and parakeets comprise the clade of long-tailed parrots which with sister clade the short-tailed Amazonian parrots and allies make up subfamily ''Arinae'' of Neotropical parrots in family ''Psittacidae'' of true parrots. There are three currently recognized species (two extant and one probably extinct), all
