Migration 25 
to May 11. Cooke (1908) took praticola in Georgia (Clayton 
County, November 30, 1907). Isley (1912) tells of this sub- 
species in Sedgwick County, Kansas (middle south region). 
Cooke (1914) in recounting the winter birds of 1883-4 at Caddo, 
Oklahoma, remarks, concerning the Prairie Horned Lark, that 
it appeared in large flocks October 26, remained constantly and 
in numbers to January, decreased from then to February 18; 
none on February 20; a few in pairs March 8. Lastly, among 
those records of birds wintering south of their breeding range, 
is that of Attwater (1892) who ealls O. a. praticola a common 
winter resident of San Antonio, Texas. 
As previously noted, the Prairie Horned Lark is absent as 
a species for a period of about six weeks to two months in the 
winter toward the northern limits of its breeding range. The 
last noted in 1925 at Evanston, IIl., was a single individual on 
November 27, the first returned January 10, 1926. The migra- 
tion dates for Ithaca, N. Y., from 1908 to 1921, are as follows:
