60 THE Birps Asout Us. 
bler 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
