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- 
count of its colour, is very noticeable. Its nest is built with 
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
