POOECETES GRAMINEUS GRAMINEUS (Gmelin): Eastern Vesper 



Sparrow 



As a breeding bird the vesper sparrow was fairly common in 

 8hady Valley from June 5 to 15, a male being taken on June 12. It 

 is probable that birds collected at 5,500 feet elevation on Roan Moun- 

 tain on September 13, 16, and 17 were local birds also. A male, 

 assumed to be in migration, was taken 7 miles northeast of Tipton- 

 ville, October 20. Other specimens in the National Museimi were col- 

 lected by W. H. Fox at Chattanooga on March 13, 1882, Lookout 

 Mountain on March 23, 1882, and Rockwood on March 6, 1885. 



AIMOPHILA AESTIVALIS BACHMANII (Audubon): Bachman's Sparrow 



The only specimens are a small series collected by W. H. Fox, in- 

 cluding birds from Lookout Mountain, April 4, 1882, and from Rock- 

 wood, April 3, 1884, and April 14, 15, 17, 22, and 25, 1885. 



That there are three geographic races of Aiinophila aestivalis in- 

 stead of the two currently recognized in the A. O. U. Check-list is 

 evident on examination of the material in the U. S. National Mu- 

 seum. A. a. aestivalis, very dark brown above, with the feathers 

 margined broadly with gray and streaked heavily with blackish, is 

 restricted to southeastern Georgia and Florida. Birds from south- 

 western Indiana and southern Illinois to southern Mississippi and 

 eastern Texas are much lighter, more rufescent-brown above, with 

 black strealdngs usually entirely absent and where present much 

 reduced. These are to be known as Aimophila aestivalis illinoensis 

 (Ridgway)." As these lines were written Sutton "^^ has identified 

 as illinoensis specimens from McCurtain County, Okla., and Ober- 

 holser ^^ has listed under this name birds from Louisiana. 



A. a. hachmanii stands midway between these two, differing from 

 A. a. aestivalis in being brighter, more rufescent, with the gray mar- 

 gins of the feathers less evident, and from illinoensis in being darker 

 brown, with prominent blackish streaks on the back. 



The birds from Tennessee, as might be expected, are definitely in- 

 termediate between hachmanii and illinoensis. One or two are closely
