292 MEMOIRS OF THE NUTTALL ORNITHOLOGICAL CLUB. 



in 1879, writes that he has been in the habit of finding these birds at Swamp- 

 scott in December, for the three previous winters, but in the winter of 1879, a 

 severe one, he had found them also in numbers in February. Mr. W. A. Jeffries 

 tells me that he had found them at Swampscott in winter as long ago as 1874. 

 Besides finding them at Magnolia in winter in 1878, I have found them at 

 Ipswich in the pitch pine thickets among the dunes since I have visited that 

 region in winter during the last eight years. I have also usually found a few in 

 the birch thickets at the southern end of the dunes and occasionally a few in the 

 woods recently planted on Castle Hill. In all these regions bayberries are 

 plentiful. It is not unusual to find twenty or thirty of these Warblers there in 

 midwinter. As a rule the winter birds appear to go north a week or two before 

 the wave of migrants from the south. 



Mr. C. J. Maynard, in a recent interesting letter to me, explains why 

 Yellow-rumped Warblers were not to be found in the early clays, 1868 to 1872, 

 in the Ipswich dunes. He says : " When I first knew the Ipswich sand dunes 

 there was not a thicket of any description on them. Consequently the Yellow- 

 rumps would not have been there. Had they been anywhere in Ipswich at that 

 time I think I should have found them. It has always been a question with me, 

 ever since it has been discovered that these birds wintered with us, as to 

 whether they have not been learning to remain north. I think I may safely say 

 that these birds did not occur in winter anywhere in the section of this State 

 over which I collected in winter." 



In the severe winter of 1904, when the cold was prolonged and intense, and 

 the snow covered the ground to such a depth that most of the bayberry bushes 

 were buried, the Yellow-rumped Warblers fared ill. On January 4th, 1904, I 

 picked up the frozen form of one of these little birds with wings spread as he 

 had fluttered down from a tree near the Ipswich dunes. From then on, until 

 April 17th, with the arrival of the spring migrants, none of these birds were to 

 be seen in the thickets of the dunes. Whether they survived the winter in more 

 protected situations I do not know.

Common transient visitor ; May 7 to May 30 ; September 13 to October 8. 



My latest date records a young bird of this species that dashed itself to 

 death against one of the lights of Thatcher's Island, in 1904. One is filled with
