BIRDS OF THE PACIFIC DISTRICT. 121 



135. Agelaius gubernator (Wagl.) Bicolored Black- 

 bird. 



San Diego, common resident. — L. B. 



San Bernardino. F. Stephens. — Common summer 

 resident of the valley. 



Cooper, 1870. I found them in scattered pairs in May 

 throughout the Coast Eange even to the summits, where 

 there are small marshes full of rushes in which they 

 build. According to my observations this species in-

 fine grass. 



Fort Klamath. Lieutenant Wittich. — Nesting in 

 great numbers. 



Willamette Valley. 0. B. Johnson. — Very abundant, 

 with habits similar to plumiiceus. 



Henshaw. This form is less abundant than phaeni- 

 ceus, as well as less generally distributed along the east- 

 ern slope. It is noticeable in this connection that none
