ANDERSON — THE BIRDS OF IOWA. 317 



how many of the Iowa records of passerinus refer to this subspe- 

 cies. Robert Ridgway (Birds of N. and Mid. Am., i, p. 20) gives 

 its range as extending "east to western Minnesota and Iowa, 

 eastern Kansas, etc." 



Two specimens from my collection, taken at Forest City, Win- 

 nebago county, one, a male, June 3, 1893, and one October 5, 

 1894, were identified by Ridgway 2A perpallidus [bimaculahis] , 

 while he identified a female from the Iowa University museum, 

 taken at Sioux City August 12, as passerinus. On August 6, 

 1897, M. E. Halvorsen showed me a nest near Forest City con- 

 taining one egg and three young birds, just hatched, in the short 

 grass of a clover and timothy field that had been mowed a few- 

 weeks previously. 



W. H. Bingaman reports the Western Grasshopper Sparrow as 

 a "common breeder" in Kossuth, and Dr. I. S. Trostler as a 

 " common summer resident " in Pottawattamie county. 



Genus Ammodramus Swainson. 



244. (547) • Ammodramus henslowi {A.n6..). Henslow Sparrow . 



The Henslow Sparrow is a tolerably common summer resident 

 in some portions of the state and appears to be rare in others. J. 

 A. Allen noted the species as less common than the Grasshopper 

 Sparrow in western Iowa, frequenting the same situations (Mem. 

 Bost. Soc, i, 1868, p. 495). T. M. Trippe found it common and 

 breeding in Decatur and Mahaska counties, frequenting the edges 

 of hazercopses (Proc. Bost. Soc, xv, 1872, p. 237). 



County records: Dallas — " taken in spring of 1895 at Perry" 

 (J. E. Law). Grund}' — "one nest found and female shot in 

 1899" (Bingaman). Johnson — a specimen taken at Tiffin, Iowa, 

 in the Bond collection, University museum (Anderson). Eee — 

 "summer resident, not common" (Currier); "scarce summer 

 resident; breeds, — Keokuk district" (Praeger). Einn — "toler- 

 ably common summer resident. I found about ten pairs of these 

 birds in 1900 breeding in a small patch of hazel and blackberry 

 briars, perhaps about a half acre in extent, and shot one for 

 identification. All had young" (Berry). Poweshiek — "toler- 

 ably common summer resident" (Kelsey); "almost common at 

 Grinnell during the whole summer" (Lynds Jones). Pottawat- 

 tamie — "scarce migrant. I have no specimens but identified 

 those killed to be the eastern bird " (Trostler).
