142 MEMOIRS OF THE NUTTALL ORNITHOLOGICAL CLUB 



22S [538] Calcarius ornatus (J. K. Towns.). 



Chestnut-collared Longspur. 



Accidental visitor from the West. 



As far as I know no bird of this species has visited the County since one was 

 so inhospitably received by me in 1876. 



[539] Rhynchophanes mccowni (Lawr.). McCown's Longspur. — An erroneous record. 



226 [540] Pooecetes gramineus gramineus (Gmel.). 

 Vesper Sparrow; Bay-winged Bunting; Grass Finch. 

 Abundant summer resident. March 26 to November 10. 

 Eggs: May 14 to June 10 (August 11). 



The courtship song on the wing is performed while the bird flies slowly not- 

 withstanding the rapid vibration of the wings, with feet hanging down, tail and 

 head elevated. In display, the male walks or runs with widely spread tail, and 

 wings spread upward from time to time. Sharp chipping notes are uttered and 

 fighting by rival males is common. 



227 [541] Passerculus princeps Maynard. 



Ipswich Sparrow. 



Winter visitor, locally common and at times abundant in autumn and early 

 winter, very rare in late winter, uncommon in the spring. October 5 to April 20 

 (May 11). 



The October 5 record is of a single bird seen at Great Neck, Ipswich, in 1913, 

 by Dr. Walter Faxon. The April 20 record is of a bird seen at Plum Island, in 

 1914, by Judge Charles F. Jenney. The unusual record of May 1 1 was of a bird 

 seen at the same place by the same observer, in 1918. My own latest spring 

 record is for April 16, 1916, a single bird seen in the Ipswich dunes. On March 

 27, 1910, I saw as many as twenty Ipswich Sparrows itl the brack on Ipswich 

 Beach. 



On March 8, 1908, I heard one sing repeatedly a feeble rather scraping 

 warble. It was not loud, not musical and not the true song. I have heard a 

 similar performance by a Savanna Sparrow in the early spring.
