Sir : I have the honor to transmit the following report upon the ornithology of the 
portions of California visited by me during the field-season of 1875. 
As a field for ornithological research, the region as a whole was by no means a new 
one, parts of California having been traversed by several governmental parties, and 
more or less extensive collections of birds made by the naturalists of the several sur¬ 
veys. The more southern portions of the State, however, those visited by us, were
