THIS is a very common summer species, and appears almost 

 always actively employed among the leaves and blossoms of 

 the willows, snow-ball shrub, and poplars, searching after small 

 green caterpillars, which are its principal food. It has a few 

 shrill notes, uttered with emphasis, but not deserving the name 

 of song. It arrives in Pennsylvania about the beginning of 

 May; and departs again for the south about the middle of Sep- 

 tember. According to Latham it is numerous in Guiana, and 

 is also found in Canada. It is a very sprightly, unsuspicious 

 and familiar little bird; is often seen in and about gardens, 

 among the blossoms of fruit trees and shrubberies; and, on ac-

 great neatness, generally in the triangular fork of a small shrub, 

 near, or among, briar bushes. Outwardly it is composed of 

 flax or tow, in thick circular layers, strongly twisted round 

 the twigs that rise through its sides, and lined within with hair 

 and the soft downy substance from the stalks of fern. The eggs
