WOOD WARBLERS 177 



on a hummock. The eggs are pure white, prettily 

 spotted with brown. The range of the Black and 

 White Warbler in summer is local over eastern 

 North America from Pennsylvania northward 

 to the latitude of Hudson Bay. They winter 

 from northern Florida southward. They are 

 slightly more than six inches in length. 



Pine Warbler. Often in late April we find 

 associated in migration with the Yellow Palms 

 and Alyrtles the Pine Warbler, so named be- 

 cause of its liking for pine trees. You will be 

 attracted by rather faint notes, which sound 

 like the utterances of the Chipping Sparrow and 

 yet are sufficiently characteristic so that you 

 will not confuse the two birds. Some observers 

 also liken its song to that of the Field Sparrow, 

 but I have not observed the likeness. The notes 

 are clear and sweet, a simple strain. Many of 

 these birds winter in the United States, even as 

 far north as North Carolina, a fact which ac- 

 counts for their early appearance in spring. 



In the breeding season the Pine Warbler is 

 closely associated with evergreen forests, espe- 

 cially the pine; therefore, its range is much 

 limited. They build in these trees, usually on a 

 horizontal line high above the ground, a com- 

 pact nest of bark, w^eeds, leaves, etc., lined with 

 feathers and hair. The four or five eggs are 

 white with cinnamon spots. 



As they usually live amid the dense foliage of 

 the pine they are rather difficult birds to ob- 

 serve. They are restive and busy, now clinging 

 to a thick cluster of needles, now moving like a 

 creeper along bough or trunk in the never end-
