138 SUMMER HOME OF DENDRCECA CCERULESCENS. 



These birds are a local race,* breeding from one generation 

 to another. They arrive from the South nearly ten days 

 earlier than those that pass through the valleys on their 

 northward migration. It is common to observe migrants 

 through the valleys while breeders on the higher mountains 

 are already nest-building and rearing their young. 



*As this subspecies does not appear to have been named, it maybe 

 called Dendroeca ccerulescens cairnsi. — E. C.
