LARK BUNTING 



Wintering in northern Mexico, and less commonly in southern Texas 

 and southern Arizona, the Lark Bunting begins its northward journey in early 

 March, but migrates so slowly that it is the first of June before it reaches 

 the northern limit of its breeding range. Its principal home is on the treeless 

 prairies just east of the foothills of the Rocky Mountains, whence it spreads 

 west in migration to southern California and has wandered east to Mount 

 Pleasant, S. C, April 19, 1895; Montauk Point, N. Y., September 4, 1888; 

 and Lynn, Mass., December 5, 1877.

The last were noted at San Antonio, Tex., on the average May 6, and the 

 latest May 13, 1899; the last in the Huachucas, Ariz., May 16, 1902; and at 

 Poway, Calif., May 25, 1886. 



The southward movement in the fall begins so early that by July 27, 1881, 

 the first appeared at Brownsville, Tex., several hundred miles south of the 

 breeding range. The average date of the first seen in southern New Mexico 

 is August 2, earliest July 31, 1901, and in southern Arizona, average August 7, 

 earliest August 5, 1909. An unusually early individual was noted July 20, 1905, 

 at Santa Barbara, Calif.
