Reveals white wing patches and tail margins when in flight. It measures approximately 23 cm long. HABITAT: Found only on San Clemente in the Pacific Ocean off the coast of southern California. Trees, shrubs, poles, fence posts, and rock outcrops provide elevated hunting perches. Nesting areas are concentrated at the island's southern end. DISTRIBUTION: Present: Found only on San Dlemente Island-one of the Channel Islands located Los Angeles County. Historic: Same as above. THREATS AND/OR REASONS FOR DECLINE: Impoverishment of esland vegetation by wheep and cattle ranching; nesting habitat degradation by feral goats; predation OTHER INFORMATION: Nicknamed "butcher bird" for practice of impaling or wedging their dead prey on twigs or dead branches to hold it as they feed or to store for later use. Mainly eat lizards, other birds, and small mammal, but also feed on insects and spiders. Courting begins in January. Nests are built form January to June.
