BIRDS OF ESSEX COUNTY. 309 



From August 15th to September 5th, 1899, they were especially common 

 in the pine thickets in the Ipswich dunes, and one or two are generally to be 

 found there every winter. 



306 [73s] Parus atricapillus Linn. 

 Chickadee. 



Very common permanent resident, especially common in winter. 



Eggs : May 4 to June 2 1 . 



It is always a pleasure to find this cheerful little bird in the pitch pine 

 thickets in the Ipswich dunes. Here in this refuge from the chilling gales, one 

 may find him throughout the winter, in company with Yellow-rumped Warblers, 

 busily engaged in gleaning the trees for larvae and in eating bay berries. 



307 [740] Parus hudsonicus Forst. 

 HuDSONiAN Chickadee. 



Accidental visitor from the north. 



I know of but two instances of the occurrence of this bird in Essex County. 

 Dearborn does not include it in his Birds of Durham and Vicinity, a region just 

 north of the County, but there are a number of records for Massachusetts 

 outside of Essex County, one from as far south as Plymouth County. 



Mr. A. A. Eaton of Seabrook, New Hampshire, writes me that in the latter 

 part of January, 1890, in a grove of pitch pines in Salisbury, he heard "a 

 wheezy Chickadee." He shot it and it proved to be hudsonicus. The specimen 

 was unfortunately destroyed by mice. This is the same bird as recorded by 

 G. M. Allen' as shot February 15th, 1890. Mr. Horace W. Wright ^ wrote me 

 in November, 1904, that on the 12th of that month he, with Mr. M. C. Blake, 

 fully identified a Hudsonian Chickadee in the cultivated larches and spruces on 

 Castle Hill, Ipswich. They saw him and heard him give his characteristic 

 calls.
