to TJngava; west side of Hudson Bay, etc. Winters in the 

 Southern States, Bahamas, Cuba. - Replaced westwardly by 

 subspecies alaudinus (Bonaparte). 



In Missouri a common transient visitant from the middle of 

 March to the first week of May and again from early in September 

 to late in November, but chiefly in April and October. It was 

 found breeding May 27, 1874, by W. E. D. Scott, near Warrens- 

 burg, where it was rather common in the spring of 1874. Mr. 

 Nehrling found it breeding at Pierce City, Mo. (W. W. Cooke), 

 and Mr. R. Ridgway at Mount Carmel in southern Illinois, the 

 nests being in damp meadows; he also took some there in the 

 middle of winter. That Mr. E. S. Woodruff found not only the 

 Vesper Sparrow, but also the Savanna Sparrow common on 

 meadows at Eudy, Shannon Co., in the midst of the heavily 

 wooded Ozark hills is interesting as it shows that even such birds 

 usually associated with open country do not follow river valleys 

 or certain prescribed migration routes, but fly broadcast across 

 the land, whether high or low, wooded or open. He found the 

 first March 19, and they became common April 28, remaining 

 so for a, whole week.

 Nebraska. Winters from the valleys of the western United 

 States and Mexico to Guatemala. 



While collecting in Shannon Co. in spring 1907, Mr. E. Seymour 

 Woodruff met with Savanna Sparrows, March 19 and 22, taking 

 specimens which proved to be 'this subspecies. On May 5 he 

 wrote that he found the species again on April 25 and considered 

 it common on and after April 28 in meadows at Eudy, Shannon 

 Co.
