BLACK-THROATED GEEEN WAEBLiEE. 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, YoUow 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. 



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.
