HERMIT WARBLER 



FROM its winter home in Mexico and Guatemala, the Hermit Warbler 

 enters the United States in April, being reported from Oracle, Ari- 

 zona, April 12, 1899, and the Huachuca Mountains, Arizona, April 

 9, 1902. Records of the first birds seen in California are Campo, April 27. 

 1877, and Julian, April 25, 1884. A Hermit Warbler was noted at Burrard 

 Inlet. British Columbia, April 20, 1885. 



In the fall the species has been noted as late as September 22, in Ari- 

 zona, and October 9, in California. 



TOWNSEND'S WARBLER 



Townsend's Warbler winters principally in southern Mexico and Gua- 

 temala: a few sometimes remain, at this season, as far north as southern 

 California. Migrants from Mexico begin to enter California, April 14 to 

 20. The earliest noted in 1888, at Chilliwack, B. C, was on May 19, 

 but the usual date of arrival is probably several days earlier, for the average 

 date of the first birds seen during five years at Columbia Falls, Mont., is 

 .May 7, varying from May 4, 1897, ^o May 11, 1896. First arrivals have 

 been noted on April 9 in the Huachuca Mountains of Arizona; Loveland, 

 Colo.. Mav II, 1889, and from Great Falls, Mont., May 28. 1890. 



KIRTLAND'S WARBLER

 Fla., April 19 and 27; St. Helena Island, S. C. April 27 and May 3; 

 St. Louis, Mo., May 8; Wabash, Ind., May 4 and 7; near Chicago, 111., 

 May 7; Rockford, 111.. May 25; Lake Koshkonong, Wis., May 24: 

 Cleveland, Ohio, May 4, 12, 13 and 15; Ann Arbor. Mich., May 14, 15. 

 16 and 18; Battle Creek, Mich., May 11; Toronto, Ont., May 16; Min- 

 neapolis, Minn., May 13; Mackinac Island, Mich., May 21. 



In the fall it has been noted at Fort .Myer, Va., September 25, and at 

 Chester, S. C, October 11.
