 Mountains, Arizona, March 31, 1885, and to Los Angeles, California, Aj)ril g, 

 1896. It does not breed at either of these localities, and the last bird in the spring 

 was seen at the former place May 10, and at the latter, May 9. The tirsl record 

 for Okanagan Landing, H. C, is May 14, 1906, and at Glacier, Alaska, June

 latest record at Los x\ngcles, California, is October 30, 1897. 



WRIGHT'S FLYCATCHER 



A few Wright's Flycatchers winter in southern California and move north 

 in April, arriving in southern British Columbia the latter part of the month. 

 The first were seen in southern Arizona, April 17, 1902. The average date of 

 arrival at Columbia Falls, Mont., is May 7, the earliest being April 24, 1895. 

 In northeastern Colorado, the average is May 11, the earliest. May 9, 1906. 



GRAY FLYCATCHER 



This species winters in Mexico, a few remaining at this season in southern 

 Arizona and southern California. It migrates north, to breed in the mountains 

 of southern Arizona and Los Angeles County, California, this short migration 

 being performed in early April. 



BUFF-BREASTED FLYCATCHER 



This is the rarest Flycatcher in the United States. It winters in Mexico,
