restless, aud was continually in motion, Hying from tree to tree, uttering its 

 well-known cries. 



^Ir. IJidijfway calls this a very interestin*; species, and states that it was 

 found very al)undant in tlie fertile canons of the West Humboldt Mountains, 

 as well as in all the extensive nut-pnie and cedar woods to the eastward. On 

 tlie Toysil»a and East Humboldt ^lou'itains, and the extensive pinon woods in 

 Soutliern Idaho, it was eiiually common. In Utah, in the canons of the 

 Wahsatch Mountains, it was occasionally seen, though oftener observed in 

 the valley of the Weber. AVhen unmolested, this bird is, he states, very 

 unsus2)icious, and anything unusual at once excites its curiosity. Often 

 when at work, in camp, skinning birds, on the edge of bushes, one of them 

 would api>roach within a few feet, and quietly watch every movement. At 

 I'nionsville they were (|uite common in the gardens and around the door- 

 yards of the town, and were very familiar and unsuspicious. Their cries 

 greatly resembled those of the California Jay, aud consisted of a repetition 

 of harsh screeching notes. 



This species, according to Dr. Coues, is a resident and a very abundant 

 species in Arizona, where it is one of the most characteristic species. It 

 was found in all situations, but seemed to slum dense pine woods, and to 

 prefer to keep on the open liillsides, among the scrub-oaks, etc. In winter 

 it collects in rather large flocks, sometimes as many as fifty together. They 

 are, however, usually seen in small groups of six or seven individuals. 

 They are said to be a restless, vigilant, shy, and noisy species. 



Mr. 0. E. Aiken found this bird a common and resident species in Colo- 

 rado. He met with it along the foot of the mountains, in brush thickets, in 

 which they also breed. The base and periphery of a nest found by him were 

 composed of dead twigs, intermingled within with fine rootlets and horse- 

 liair. The eggs, four or five in number, are said to be laid about the first of 

 May. They have a ground-color of a light bluish -green, and marked with 

 reddish-brown specks, thickest at the larger end. They are of a rounded 

 oval sha])e, much more pointed at one end, and rounded at the other, and 

 average 1.U6 inches in length by .80 of an inch in breadth.
