Rounded Global Status Rank: G1 - Critically Imperiled

Reasons: Historically widespread in California, Oregon, Arizona, and Mexico, declined to extirpation in the wild by the 1980s; captive breeding increased the number of individuals and allowed releases; reintroduction efforts are in progress in California, Arizona, and Baja California, with limited breeding and fledging success; reestablishment of self-sustaining wild breeding populations is uncertain, in part because of environmental perils such as lead poisoning and trash ingestion that are difficult to manage.

Intrinsic Vulnerability: Highly vulnerable

Comments: Low breeding rate and slow maturation.
