Vol. IX] MAILLIARD— AVIFAUNA OF THE INNER COAST RANGE 277 



often in southern California in winter, but no well populated 

 wintering ground south of Napa County has yet been found. 



A few fox sparrows of other forms were found among the 

 Yolla Bolly which were evidently passing migrants, on their 

 way to their more northern breeding grounds. 



The weather during our stay here was chilly most of the 

 time, rainy and consequently gloomy some of the time, and 

 far from favorable for such observations as we wished to make, 

 and as we were working almost altogether in the forest or 

 brush of the Transition zone, this may account in part for our 

 small list of birds noted. In addition to this, most of the winter 

 visitants had left and it was too early for the summer influx. 

 This latter fact, however, was to our advantage in that we 

 could note the date of arrival of the summer visitants as they 

 appeared. The Western Flycatcher was the only species of the 

 latter found in the higher altitudes at this date, the first being 

 noted on April 1. 



The Sacramento Towhee seems to be the race inhabiting this 

 locality, and is true to form as regards relative size of feet, but 

 in coloration it appears to intergrade with falcifer, whose ter- 

 ritory lies only some twenty or thirty miles westward in the 

 more humid strip near the coast. 



The Northern Brown Towhee of this region also somewhat 

 approaches the coast form, crissalis, but can be easily dis- 

 tinguished. The Black-throated Gray Warbler was found in 

 Transition here, and there seems to be every probability of its 

 nesting, but this was not proved, few individuals being seen and 

 none taken. Fisher mentions this species as being very numer- 

 ous at the time of his visit in the late summer. 



This locality was last visited on May 3, to ascertain if the 

 Yolla Bolly Fox Sparrows were breeding here. That after- 

 noon Mr. Little went up to the top of the first peak, while I 

 remained lower down at the levels in which we had taken them 

 previously, but not an individual was seen nor a note heard. 

 It is barely possible that some might be breeding on one of the 

 other peaks, neither of which is very much higlier than the 

 south peak we were on, but bad weather with dense fog set in, 

 after a hot spell we had been having, showing signs of con- 

 siderable duration. There being small likelihood of our finding 

 any fox sparrows there the idea of further investigation was
