NOTES ON THE HENSLOW'S SPARROWS (Amnio- 



drannis hcnslowii) IN MAHONING COUNTY, OHIO. 



BY EARNEST W. VICKERS. 



In July, 1907, I discovered that we had suffered an invasion 

 of Henslow's Sparrows at Ellsworth Station, Mahoning 

 County, Ohio, where for almost ten years I have carried on 

 bird observations. 



On July 11, while haying in a 14-acre meadow of very heavy 

 upland grass, the fact suddenly dawned on me that a new spar- 

 row voice was all about, and to be heard above the rattle of the 

 hay wagons, and clatter of loader, tedder and olher noisy hay- 

 making machinery. 



It occurred that I had lieard the strange voices for several 

 days, but I was imable to say how long. The shrill, quaint 

 cry sounded like "tis-zeek, tis-zeek," accented en the last syl- 

 lable, sometimes changed to "tip-see. tis-zeek." 



There was a ventriloquial quality about it, for it seemed to 

 be equally remote and near, like the thinner strain of the Grass- 

 hopper Sparrow, which I had first observed for Ellsworth in 

 1895. 



When one of these newcomers at length revealed himself, he 

 proved one of the most nervous, excitable of birds and would 

 crouch down and rise up as if about to take wing after the 

 manner of the Meadowlark, turn round and round, all nervous 

 and fussy at being approached, giving utterance to his sharp 

 and characteristic call. I spent several evenings with them 

 after work and secured three males highly developed sexually. 

 There were from nine to twelve males in this single meadow, 

 and examination of neighboring fields revealed no more. 



The calling birds probably represented so many pairs.
