BIRDS — CORVIDAE — CYANOCITTA WOODHOUSEII.

crescent, white streaked witli blue ; lieliind it dull white ; the sides tinged with brown. Length, 12.25 ; wing, 5 ; tail, G.15 ; 

 tnrsns, 1.55. (2841.) 



Hub. — I'acific coast from Columbia nver south. Not in the interior. 



The foreliead and nasal feathers are uniform blue with the crown. The blue extends on the 

 fore part of the back ; it is scarcely found on the rump, although the upper tail coverts are like 

 the crown. There is no trace of blue on the belly, although a very faint wash is perceptible on 

 the lower tail coverts. The blue streaks on and anterior to the pectoral collar are on the edges 

 of the feathers, not the centres. 



I find considerable diiferences in size in different specimens of this bird. Thus, No. 8456, 

 from San Francisco, measures nearly 14 inches ; the wing, 5.25 ; the tail, 6.40. No. 8455, 

 (male,) from Tejon Pass, on the contrary, measures 10.40 inches; the wing, 4.65; the tail, 

 5.50. The more southern specimens are smaller, and have the ashy brown of the back less 

 glossed with blue. In most specimens the tail feathers are nearly truncate ; in 2841, however, 

 they are quite acute. 



In young birds the head is generally like the back, with only a faint shade of blue. There 

 is a brownish j^ectoral collar, but no streaks of blue.
