2 70 MEMOIRS OF THE NUTTALL ORNITHOLOGICAL CLUB. 



233 [560] Spizella socialis (Wils.). 

 Chipping Sparrow; Chippy. 



Abundant summer resident ; (March 24) April 9 to October 28 ; average 

 date of arrival for ten years, April 7. 



E^^s: May 23 to June 26. 



Besides the usual wirey trill, this bird may occasionally be heard to warble 

 quietly and softly. 



234 [563] Spizella pusilla (Wils.). 

 Field Sparrow. 



Common summer resident ; April 2 to October 26. 



E^gs : May 21 to June 12. 



At the height of the season, the Field Sparrow sometimes repeats his 

 lovely song five times in a minute. It is certainly one of the sweetest songs we 

 have. 



23s [567] Junco hyemalis (Linn.). 

 JuNCO; Snowbird. 



Abundant transient visitor, not uncommon in winter ; (September 3) Sep- 

 tember 26 to November 30 ; winter ; March 8 to May 2 (May 21). 



The unusual record for May 21st, was made by Mr. Hoffmann who found a 

 single bird at Ipswich on that date in 1904; and the September 3d record is of 

 a bird I saw at Groveland in the same year. 



The Junco has, besides the trill which varies considerably, resembling some- 

 times the metaUic tinkle of a cow-bell, a low sweet warble, which also varies, and 

 sometimes recalls the song of the Goldfinch. While with us, they are particu- 

 larly apt to sing if they are in the company of a singing band of Fox Sparrows, 

 and I have heard them sing their warbling song in October. The first arrival in 

 1903, on September 28th, alighted on one of the handles of the wheelbarrow 

 between which I was standing.
