The Western Scrub Jay

Color Pattern - Blue and gray above, with a pale underside broken up by a blue necklace. In birds, the color blue depends on lighting, so Western Scrub-Jays often look dark.

Behavior - Assertive, vocal, and inquisitive. You’ll often notice scrub-jays silhouetted high in trees, on wires, or on posts where they act as lookouts.

Habitat - Look for Western Scrub-Jays in open habitats of the West: oak woodlands and chaparral near the coast and pinyon-juniper woodlands of the interior West; also backyards, pastures, and orchards. (From Wikipedia)
