BLACK-THROATED GREEN WARBLER. 247 
Abundant summer resident. Breeds. Arrives the last of April and 
remains until September. The Yellow Warbler or Summer Yellowbird, 
or, as it is frequently though incorrectly called, Yellow Wren, is the best 
known bird of this family. It frequents the banks of streams, 
orchards, gardens and groves, and is quite at home in the shade trees of 
the city. It is rarely seen in dense woodland. The males are in full 
song on their arrival. 3 
The nest is placed in an upright fork of a small branch of a tree or 
bush ; in gardens, the pear tree is a favorite situation. It is composed of 
vegetable fibers and down, and lined with hair. The eggs are usually 
four, white, with a greenish tinge, spotted with different shades of brown 
and lilac. Two broods are frequently raised in a season.
