- Color Pattern
Light blue and gray above, with a whitish throat and grayish belly separated by an indistinct, partial breast band of blue. In birds, the color blue depends on lighting, so Woodhouse's Scrub-Jays can look simply dark.

Assertive, vocal, and inquisitive. You’ll often notice scrub-jays silhouetted high in trees, on wires, or on posts where they act as lookouts. In flight seems underpowered and slow, with bouts of fluttering alternating with glides.
- Habitat
Look for Woodhouse's Scrub-Jays in open habitats and pinyon-juniper woodlands of the intermountain West; also backyards and pastures. Typically, though not always, in lower and drier habitats than Steller’s Jay.

Regional Differences
A subgroup of Woodhouse's Scrub-Jay occurs in southern mainland Mexico and is sometimes called "Sumichrast's" scrub-jay. Compared with the Woodhouse's in the U.S., these show more contrast between blue upperparts and white underparts, and have a less distinct blue necklace. On the Edwards Plateau of Texas, Woodhouse's Scrub-Jays are darker blue with a narrower necklace, browner underparts, and a heavier, less pointed bill.
