The principal object in visiting this place was to ascertain 

 if any fox sparrows might be breeding on the mountain, but, 

 although there seems to be sufficient brush of suitable sort 

 to attract them, it was evidently not at a high enough altitude 

 to meet their needs. 



A few individuals of small-billed races of fox sparrows 

 were still loitering on their northward journey to their distant 

 breeding grounds, of which one or two were taken, but no 

 Yolla Bollys. 



Except for the species commonly found about gardens and 

 dwellings in this central part of California, birds were notably 

 scarce, although there was water in abundance in the springs 

 and small streams — the latter in ravines too steep and rough 

 for us to follow far. A number of Sonoma Thrashers inhabit 

 the brushy hillsides, and their diversified vocal outpourings 

 were most pleasing. At times none could be heard, at other 

 times one or two would break into song for short periods, while 

 again other individuals, from the top of some bush, would go 

 through their entire repertoire only to repeat it again and again 

 until a real or fancied danger caused a sudden dive into the 

 thicket. The Pallid Wren-tit (Chamcea fasciata henshazvi) , 

 also was here in abundance, in some parts their peculiar trilling 

 notes seeming to come from all sides. Other birds and small 

 mammals being so scarce and hard to find, a move was made on 

 the morning of April 27 to 



Glenbrook, Lake County, California 



At one time a well known resort for hunters and fisher- 

 men, this place at present is conducted as a sort of farm that 

 will accommodate guests if they appear. It is situated at the 

 northern base of Mt. Cobb, 12 miles west of Middletown on 

 the road to Kelsey^^lle and Lakeport, and is also on Kelsey 

 Creek, which flows into Clear Lake. It is three miles west 

 of Cobb P. O. in Cobb Valley, at an elevation of about 2300 

 feet, the divide, between this valley draining into Clear Lake 

 and the Middletown Valley draining into the Sacramento 

 River basin, being a short distance above Cobb. Here we 

 found the vegetation much behind what we had so far been 

 encountering, it being at about the same stage as that on Mt.
