tree, from fifteen to one hundred and thirty-five feet above the 

 ground, and is constructed outwardly of strips of bark, slender 

 twigs, and weeds, while the interior is lined with feathers, hair, and 

 plant down. Although the nest is attached to the limb with cater- 

 pillar silk, which is very tenacious, it is sometimes blown away 

 by the severe windstorms which frequently occur in March, thus 

 forcing the birds to build again. . 



The first nest may contain four eggs, while the second usually 

 numbers three. Sometimes three broods are raised, but this is 

 unusual. The eggs are white or greenish white, spotted and 

 blotched with umber, reddish brown, and Hlac. They measure 

 .70.x. 52. 



266. Dendroica palmarum (Gmel.). Palm Warbler. 



On September 7, 1896, I shot a typical specimen of this form 

 near Mount Pleasant. This is my earliest record and the species 

 is never common until September 22. Great numbers are regu- 

 larly seen during October and November. 



While this warbler is a regular winter visitant, it appears more 

 frequently during severe winters than in milder ones. The 

 winter of 1904 was very severe and Palm Warblers were especially 

 abundant, many being killed by the cold weather. The following 

 winter was also very cold and I observed numbers of birds almost 

 daily. In the winter of 1906, however, I did not observe more 

 than a dozen individuals in January and February, despite the 

 fact that it was the mildest winter since 1890. 



The birds migrate very early in the spring and long before they 

 have acquired their summer plumage — my latest record being 

 April 5. At Darien, Georgia, I took a belated example in full 

 breeding plumage on May 16, 1891. 



While migrating, the birds frequent fields as well as the sandy 

 wastes on coast islands which are covered with wild oats and 

 scattered bushes. 



The Palm Warbler breeds in the interior of British America, 

 Fort Simpson, Fort Resolution, and Fort Churchill.

 Warbler; Yellow Redpoll Warbler. 



The Yellow Redpoll Warbler arrives from the north about 

 October 10, and a few remain during some winters. It is never
