HAMMOND'S FLYCATCHER 



Wintering south of the United States, this species returned to the Catalina 

 Mountains, Arizona, March 31, 1885, and to Los Angeles, California, April 9, 

 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 first record 

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

 8, 1899. 



The first fall migrants were noted in the Huachuca Mountains, Arizona, 

 August 26, and the last, in the Catalina Mountains, Arizona, October 25. The 

 latest record at Los Angeles, 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 n, 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, 

 a few coming north to breed in southwestern New Mexico and southern Arizona. 

 They arrived in the Huachucas, Arizona, April 20, 1902, April 12, 1903; Santa 

 Rita Mountains, April 20, 1899, and in the Chiracahua Mountains, Arizona, 

 April 12, 1880. 



WESTERN FLYCATCHER 



This form replaces the Yellow-bellied Flycatcher from the Plains to the 

 Pacific. It arrived in the Huachuca Mountains, Arizona, April 10, 1902; Terry, 

 Mont., May 18, 1894, May 19, 1896; southern California, average March 20,
