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 September. According to Latham it is numerous in Guiana, and 
is also found in Canada. It is a very sprightly, unsuspicious and fami- 
liar little bird ; is often seen in and about gardens, among the blossoms 
of fruit trees and shrubberies ; and, on account of its color, is very 
noticeable. Its nest is built with great neatness, generally in the tri- 
angular fork of a small shrub, near, or among, briar bushes. Out- 
wardly 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 ea:ars 
are four, or five, of a dull white, thickly sprinkled near the great end 
with specks of pale brown. They raise two broods in the season. 
This little bird, like many others, will feign lameness to draw you aAvay 
from its nest, stretching out his neck, spreading and bending down his 
tail until it trails along the branch, and fluttering feebly along to draw 
you after him ; sometimes looking back to see if you are following him, 
and returning back to repeat the same manoeuvres in order to attract 
your attention. The male is most remarkable for this practice.
