Numbers of these were seen nesting in the mesquite on the prairies, at which time thej were very musical, and having 

 sometimes as many as three nests in the same tree ; the nests were built of fine grass, in the tops of the branches, and interwoven 

 among the leaves. — (Clark )

Jn passing through the Guadalupe canon this bird was often seen, but at no other point on the route was it observed. It 

 reemed to prefer the low bushes on the hill sides to the large trees. In its motions it was quick and restless, passing rapidly 

 from bush to bush. — (Kennerly.)

Docs not seem to possess the cunning or wariness of its congene-s. Found most abundantly ahout watering places; not 

 habitually in great flock*, though at the head of the Limpia many were congregated and flying about the face of an immense 

 rocky mou tain wall, where they were probably nesting. Their note is coarse and less shrill than the common crow. Met 

 with a nest in an arooresceiit cactus? — ^Clark.) 



Found in small numbers in eastern Tamaulipas, generally near ranches. — (Couch.) 



Not very con.mon, and when seen generally associated with the larger species of the same genus. — (Kennerly.)

Kear Copper Mines. 



At the Copprr Mines a great many jays of this and allied species were seen, usually feeding, in parties of a dozen or more, 

 oil the pinoles and acorns. The harsh, disagreeable note of one of these wary birds is the signal of alarm for all the rest ; even 

 in llieir undisturbed course of feeding they go over a great deal of ground, the one in the rear advancing in front of his file 

 leader, all the while keeping up their grating music, and thus each knowing the whereabouts of the other.
