298 MEMOIRS OF THE NUTTALL ORNITHOLOGICAL CLUB. 



288 [679] Geothlypis Philadelphia (Wils.). 

 Mourning Warbler. 



Very rare transient visitor ; May and September. 



Mr. G. O. Welch tells me that several birds of this species have been 

 taken in Essex County. He heard its characteristic song in Lynnfield about 

 fifteen years ago in the spring, and his companion, Mr. Moon, shot the bird. 

 Mr. E. M. Haskell has a specimen in his collection taken by him in Lynn in 

 May, 1882. 



289 [68 id] Geothlypis trichas brachidactyla (Swains.). 

 Northern Yellowthroat ; Maryland Yellowthroat. 



Abundant summer resident ; May 6 to October 19 (December 6). 

 Eggs : May 24 to June 13. 



I found a Maryland Yellowthroat on December 6th, 1903, in the sand 

 dunes just back of Ipswich Beach, among some bay berry bushes and golden- 

 rod stalks. There was about an inch of snow on the ground and the thermome- 

 ter early in the morning was only 1 5 Far. The bird proved to be a young male, 

 quite fat, with its stomach filled with insects, mostly beetles and flies, and a few 

 small seeds. Its plumage was interesting, as it had already partially assumed 

 the first nuptial plumage. 



It is interesting to speculate as to what might have been the fate of this 

 young bird had he not been shot. He had evidently been entirely deserted by 

 his companions and it is very doubtful whether he could have found his way 

 south, and still more doubtful if he could have survived the winter in the 

 north. 



290 [683] Icteria virens (Linn.). 

 Yellow-breasted Chat. 



Not uncommon local summer resident ; May 10 to September. 

 Eggs: May 30 to June 18.
