BIRDS OF ESSEX COUNTY. 269 



230 [554] Zonotrichia leucophrys (Forst.). 

 White-crowned Sparrow. 



Uncommon transient visitor ; May 1 2 to May 24 ; October 3 to ; 



average date of arrival for four years, May 1 5 . 



At times this handsome bird is not uncommon in the spring. Mr. W. A. 

 Jeffries notes this at Swampscott, in 1876, and says they were quite tame. I 

 have seen four on May 20th, 1900, feeding on some grain dropped within two 

 feet of the door-steps of my summer house at Ipswich. 



2 3 l [SS 8 ] Zonotrichia albicollis (Gmel.). 

 White-throated Sparrow ; Peabody-bird. 



Common transient visitor ; April 1 5 to May 2 1 ; September 2 1 to Novem- 

 ber 1 1 . 



In the autumn, one may not infrequently hear a faint lisping caricature of 

 their glorious spring song- This is, I suppose, the effort of immature birds. 



232 [559] Spizella monticola (Gmel). 

 Tree Sparrow. 



Abundant winter visitor ; October 7 to April 22. 



The Tree Sparrow is one of the common winter birds in the thickets 

 among the sand dunes. 



On January 15th, 1904, I was attracted by the chirping of this bird at 

 1 1.30 p. m. on the Public Garden, in Boston, and saw one hopping about on the 

 snow near an electric light. It was soon joined by another, and both flew away 

 chirping.
