Very local, long-tailed, and social parrot of mountains in northwest Mexico. Feeds in pine and pine-oak forests. Nests colonially in groves of giant aspens, whose soft trunks allow nest cavities to be excavated. Usually found in flocks, of 10–100 birds, less often in scattered pairs; often located by its far-carrying, raucous laughing calls. No similar species in its range; note the red forehead and small red shoulder patches. In flight shows a broad yellow stripe under the wings.
