INASMUCH as there are four records of the appearance of this 

 warbler in California, it may be reckoned casual, or even "rare migrant," 

 rather than accidental; and we may hope to welcome it again. Indeed, 

 all the evidence would go to show that there is every year a certain small 

 percentage of eastern species which comes up or goes down the wrong 

 side of the Rockies, in the attempt to pass to and from the breeding 

 grounds in Alaska and Yukon Territory. These may be regarded either 

 as wanderers blown out of their course by adverse winds, or as adventurers, 

 unconscious pioneers, scouting out new flylines for their respective 

 species. The presence of an occasional foreigner among our regular 

 migrants may also be accounted for by pleasant entanglements formed in 

 the Southland, Mexico, or Panama. Yet it is also noticeable that these 

 waifs do go in bands of associated eastern species, . 



detached fragments of that brilliant army of in- 

 vasion which, billions strong, annually 

 sweeps the East in a resistless, joyous tide. 

 We do not, of course, de- 

 tect a thousandth part 

 of the strangers among 

 us, for they pass 

 unheeded through 

 the wastes of chap-
