60 THE BIRDS ABOUT Us. 



bier is the " Black-and- White Tree-creeping" one, 

 that here, too, is a resident, making a neat nest on the 

 ground, but living in the trees even more closely 

 than most of the family. In its movements it is 

 quite like the brown tree-creeper already noticed. 

 This species is really quite hardy, and braves a good 

 deal of cold, and yet is stated to be one that quickly 

 seeks a semi-tropical climate when our winter ap- 

 proaches. I believe they do not all leave their 

 summer haunts, for they are back again in April, 

 when we are apt to have quite cold storms that do 

 not disconcert them. 



Another summer resident in the Delaware Valley, 

 but one that varies in numbers year after year, is 

 the Worm-eating Warbler. Its brown head with dis- 

 tinct darker streaks render it easily recognized, and 

 in Southern New Jersey the Parula and Hooded 

 Warblers tarry all summer, while more than one 

 " Canadian" form is to be found nesting in the hem- 

 lock swamps of Northern Pennsylvania. 



But to see the warblers in their glory ; to hear the 

 music they are capable of performing ; to know them 

 at their best, it is necessary to visit the woods and 

 wastes of Canada and Northern New England. Their 

 presence, at such a time, makes the country south of it 

 almost commonplace. The birds of the region known 

 as the Carolinian fauna are well enough in their way, 

 but their united efforts do not eclipse the northern 

 woods in the time of the nesting warblers. 



There is one warbler, however, that for beauty and 

 vivacity, and with some pretension to song, is almost 

 the equal of the brilliant migrants. I refer to the
