A large and sometimes conspicuous macaw of Bolivia’s interandean dry valleys. This species is critically endangered, but can sometimes be locally common, especially near tall cliffs cut in hillsides by rivers. Often forages in and around agriculture. The only large, green macaw in its range. Fairly similar to Military Macaw, but shows orange fold to leading edge of wing, no bare facial skin, and a dark gray bill. Often noticed by loud, raucous voice.
