D. PALMARUM : YELLOW RED-POLL WARBLER. 151 



the middle of that month, and passes on with Httle 

 delay through the Alleghanian Fauna, being scarcely 

 seen in Massachusetts after the first few days in May. 

 Returning in September, it lingers leisurely through 

 that month, all of October, and part of November, 

 before taking its final departure. Like the Pine- 

 creeping and Yellow-rump, it is a Warbler which 

 may be associated with frozen ground and snow- 

 storms, and there is just a suspicion that it may be 

 found, at times, the winter through. Thus Mr. Mer- 

 riam : " Along with D, -piniis and D. coronata it may 

 be seen, in spring, long before the hosts of other War-

 to depart in the fall, at which time it is found along 

 fences, and among low bushes, by the roadside, and in 

 open fields. In early spring, before the snow has quite 

 all disappeared, large numbers of them may some- 

 times be seen, in company with the English Spar- 

 rows, running about on the plots of bare ground, and 

 the roots of the elm-trees, on the City Green, in the 

 heart of New Haven. In fact, they seem to pay but 

 little attention to the weather, as may be seen from the 

 circumstance that they were really abundant on the 

 i8th of April, 1875, '^^ '^ time when the ground was 

 covered with snow nearly a foot deep, with only here 

 and there a bare spot ; while none were seen this sea- 

 son (1877) till April 13th, notwithstanding the fact 

 that the ground had been bare since the latter part of 

 March, and the weather unusually mild." (Rev. B. 

 Conn., 1877, p. 18.) 



The species breeds for the most part far to the north, 

 and is entirely restricted southward in the nesting sea- 

 son by the Canadian Fauna ; being so rare in sum-
