442 LAND BIRDS 



it is a most difficult bird to observe during the nesting 

 season. 



The food of hammondi consists of insects, which it 

 catches by darting from its perch. In sharp contrast to 

 the restless energy so characteristic of its family, it will 

 sit motionless for a long time upon this perch, Micawber- 

 like, waiting for something to turn up. It is compara- 

 tively little observed, and is accounted rare, but I believe 

 this is due more to its retiring habits and silence than to 

 any special scarcity of individuals. It is certainly not 

 uncommon in the higher valleys of the Sierra Nevada in 

 June, and would, I believe, allow some investigation of 

 the nesting habits without deserting the brood, for the 

 parents are very devoted.
