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.
