Nest, bulky, of strips of bark, coarse grasses, and dead leaves, lined with

One of the first acquaintanoes you will make, when you begin to 

 look for birds, will be this black-masked inhabitant of thickets and 

 bushes. Indeed, you have only to pause near his home, when he 

 will meet you halfway. He announces his coming by an impatient, 

 quickly repeated chack, varying to chit, pit, quit, as, hopping from 

 twig to twig, he finally appears for a moment and then darts back 

 into the cover of his haunts. 



His song is characteristic of his active, nervous nature, and is de- 

 livered with much force and energy. It varies greatly with locality, a 

 fact which may account for the quite different descriptions given of 

 it by authors. Sometimes it is written wichity, wichity, wichity, 

 michity ; again, rapity, rapity, etc. : but the birds near New York city 

 seem to me to say 1 beseech you, I beseech you, 1 beseech you, I beseech 

 you ; though, to be sure, the tone is far from pleading. 



They sing throughout the summer, and in August add a flight 

 pong to their repertoire. This is ustially uttered toward evening, when 

 the bird springs several feet into the air, hovers for a second, and then 

 drops back to the bushes.
