COMMON BIRDS: SECOND SERIES.

Black-throated Green Warbler. 12. 
[dENDRIECA VIRENS.] 
The frequent visitor to deep pine woods is struck with a curi¬ 
ous, insect-like song which ( is incessantly repeated from the waving 
tops above him. Two wheezy notes, followed by two higher ones, 
either lazily drawled or quickened in double time, make up the 
performance. A glance at the bird shows a black throat and 
yellow cheeks ; the green which is included in the name is rarely 
visible in the live bird. In cedars, pitch pines, and white pines, 
the Black-throated Green Warbler is a common bird from early 
May to the end of summer. Migrants from the north pass 
through New England as late as October. The nest of this little 
bird with the cumbersome name is neatly built of twigs, bark, 
and grass, lined with feathers or hair, and placed on a fork or 
branch of an evergreen. The eggs are three or four, white, marked, 
chiefly at the larger end, with reddish spots. Like all its family, 
this Warbler lives on insects which it finds in trees. It is oftenest 
seen on migration, when it visits the orchards and copses. In 
winter it passes across the Gulf to Central America. 
Pine Warbler. 18. 
[dendrceca vigorsii.] 
The Pine Warbler is the first of its family to arrive in the 
spring, and often lingers late in the fall. On some warm morning 
in the first week of April, a lazy trill sounding among the pitch 
pines announces the bird’s arrival. Its whole summer is spent in 
the tops of the pines, either in the low, open groves of the pitch 
pine, or in the tall, dense tops of the white pine. Like many of the 
wood-warblers, it is oftener heard than seen, but in spring, when 
migrating, the Pine Warbler visits the orchard trees, and occasion¬ 
ally feeds for a moment on the ground. The nest is built in 
the pines, generally among the needles toward the end of a limb.
