Cleptes nuttalli, Gambel, J. A. N. Sc. Ph. 2d Series, I, 1847, 46. 
Sp. Ch.—B ill, and naked skin behind the eye, bright yellow ; otherwise similar to P. hudsonica. Length, 17; wing, 8; 
tail, 10. 
Hab. —California. 
This species, in every appreciable respect, is precisely similar to the common magpie, with 
the exception of the hill and naked skin around and behind the eye, which are bright yellow. 
Sometimes this is rendered darker from the fact that the transparency of the horny covering ot 
the hill allows the hone to he seen through it. The size is rather smaller, but this may he the 
result of its more southern locality. It is a very serious question, whether the bird is anything 
more than a permanently yellow-hilled variety of the common bird. It is well known that in 
Psilorhinus morio, and other garruline birds, the hill may he either yellow or black, almost in 
the same brood of young ; and if magpies with these differences were habitually associated 
throughout the continent, there would probably be no hesitation in combining them. The 
restriction of the yellow billed magpie to the coast region of California, where it is unmixed 
with black billed individuals, except in the northern portion of the State, is an interesting fact.
