Habits. Bullock's Oriole, the western counterpart of the eastern IJalti- 

 niore, is fonnd throughout the Pacific shore, from tiie great Central Plains to 

 the ocean, and from Washington Territory to ^lexico. It is not given by 

 Suinichrast as occurring in Vera Cru/, where its place is taken, as a migrant, 

 by the liiiltimore. It was not noticed by jNIr. Dresser on the Itio (irande, 

 but in Arizona it was found by Dr. Cones to be a common summer resident. 

 It was there seen to frequent, almost exclusively, the willows and cotton- 

 woods of the creek-liottoms. To the small twigs of these trees its pensile 

 nests were usually attached. It is said to arrive in Arizona late in Ajjril, 

 and to remain tliere nearly through September. 



In the survey of tiie Mexican boundary Dr. Kennerly met with this 

 species in passing through Guadaloupe canon, where it was often seen, but 

 it was observed at no other point on the route. It seemed to prefer the 

 low bushes on the hillside to the large trees. In its motions it was quick 

 and restless, passing rapidly from bush to bush. 



In Washington Territory this species is stated by Dr. Suckley to be more 

 abundant in the .sparsely wooded districts of the eastern base of the Cascade 

 Mountains than in the Coast liange. He found it exceedingly abundant at 

 Fort Dalles and along the eastern base of Mt. Adams. They arrive about
