Steller's Jay

Steller's Jay (Cyanocitta stelleri): A native Jay with a long dark gray or black crest, a dark head and a blue body and tail feathers. They are common in coniferous forests and mixed woods. Two varieties include the Pacific, found along the coast from Southern California to Alaska, and the Interior West, found in the Rocky Mountain region of the U.S. and Canada. The males of the Interior West variety have white markings on the forehead.  

I saw a Steller's Jay on a run in Golden Gate Park. I remember the difference between Steller's Jays and Scrub Jays because the long crest, which looks like a mohawk to me, is "stellar," and the Scrub Jay is "scrubbed" of it's mohawk.
