The Steller's Jay shows a great deal of regional
variation throughout its range. Blackish-brown-headed
birds from the north gradually become bluer-headed
farther south. The Steller's Jay has a more slender bill
and longer legs than the Blue Jay and has a much more
pronounced crest. The head is blackish-brown with light
blue streaks on the forehead. This dark coloring gives
way from the shoulders and lower breast to silvery blue.
The primaries and tail are a rich blue with darker
barring. ...info from Wikipedia
