Woodhouse's Scrub-Jays are medium-sized birds of the corvid family, a group known for their gregarious behavior and intelligence. They live in the western United States and down into central parts of Mexico. They live in inland forest habitats. In late 2016 the species Western Scrub-Jay was split by many taxonomic authorities into the Woodhouse's Scrub-Jay and the California Scrub-Jay.
Like many other corvid species, Woodhouse's Scrub-Jays cache surplus food for future use. They may also steal food from other bird caches and take measures to protect their own food stores from theft by other birds.
The common name of this species honors the American doctor and naturalist Samuel Washington Woodhouse. There is also a toad named in his honor.
