 lets, sometimes lined with horsehair. Eggs : 4 to 7, glossy green, un-

Food. Largely acorns ; but also grasshoppers and other insects, wild 

 fruits and seeds. 



The Arizona jay is an abundant resident of the live-oak belt of 

 the Chiricah.ua, Huachuca, Santa Catalina, and some of the other 

 Arizona mountains, from an altitude of from 3000 to 7000 feet. In 

 severe winter weather the jays sometimes come about houses, and 

 can be attracted by bones or meat hung on trees. Although their 

 principal food is acorns, when they are out of season the birds de- 

 pend largely on grass, seeds, grubs, beetles, young birds, and eggs. 

 In habits, Mr. Scott says, the jays are as terrestrial as crows.

 sides of head bright azure blue ; throat dull white ; breast brownish gray ; 

 belly and under tail coverts pure white. Length: 11.50, wing 5.80-5.1)0,

 Mountains. 



Nest. Made of sticks, lined with rootlets. Eggs : 4, robin's-egg blue. 



In the Chisos Mountains, Texas, Mr. Bailey, Mr. Fuertes, and Mr. 

 Oberhoiser found the Couch jay, which was previously known only 

 in Mexico, common from the lower edge of the oaks and junipers to 

 the top of the range. It was especially abundant in the shady gulches 

 near water. Like most other jays, though noisy and conspicuous, 

 it was shy and suspicious. During the first half of June old and 

 young were flying together, busily catching and eating the large cica- 

 das that swarmed in the oaks.
