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. [8] Steller's jay has a more slender bill and longer legs than the blue jay and, in northern populations, has a much more pronounced crest. [9]: 69 [10] It is also somewhat larger.
Crested jays are relatively slender corvids with similar body shapes but differ in size. Steller’s jay is larger than the blue jay.
