The Western Scrub-Jay (Aphelocoma californica), is a species of scrub-jay native to western North America. It ranges from southern Washington to central Texas and central Mexico. It comprises three distinct subspecies groups, all of which may be separate species. They are California Scrub-Jay (coastal), Woodhouse's Scrub-Jay (interior US and northern Mexico), and Sumichrast's Scrub-Jay (interior southern Mexico). The Western Scrub-Jay was once lumped with the Island Scrub-Jay and the Florida Scrub-Jay; the taxon was then called, simply, the Scrub Jay. The Western Scrub-Jay is nonmigratory and can be found in urban areas, where it can become tame and will come to bird feeders. While many refer to scrub-jays as "blue jays", the Blue Jay is a different species of bird entirely. In recent years, the California Scrub-Jay has expanded its range north into the Puget Sound region of Washington (wikipedia).
