62 YELLOW-THROATED WARBLER 



Most of them soon pass on north or into the coun- 

 try, but some always remain to nest in the parks and 

 gardens of the city. They build in shrubbery or in 

 the smaller trees, and the nest is usually in an upright 

 fork. Fine grasses and plant-down are the choice 

 materials used, very compactly woven together. The 

 eggs, 4 to 5, are bluish white, thickly speckled with 

 brown. 



In the country these Warblers are frequently im- 

 posed upon by the Cowbird, Init they show great 

 ingenuity in getting rid of the obnoxious egg by 

 l^uilding a second story to their nest, thus covering it 

 out of sight. 



Yellow Warblers are among our most useful bird 

 citizens, for besides winged-insects they eat canker- 

 worms, spiders, plant-lice and small beetles.

This handsome Warbler frequents woods that bor- 

 der streams, but he is a southern bird and is seldom 

 seen as far north as this. His song is said to 

 resemble that of the Indigo-bird.

 4 to 5, are thickly speckled with brown.
