Turis 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 afew shrill notes, uttered with 
emphasis, but. not deserving the name of song. It arrives in Penn- 
sylvania 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 isalso found in Canada. It is a very sprightly, unsuspi- 
cious, and familiar 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 triangular fork of a small shrub, near or among brier 
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 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 away 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 manceuvres, in order to attract your attention. The male is 
most remarkable for this practice. 
The Blue-eyed Warbler is five inches long, and seven broad; hind 
head and back, greenish yellow; crown, front, and whole lower parts, 
rich golden yellow ; breast and sides, streaked laterally with dark red ; 
wings and tail, deep brown, except the edges of the former, and the 
inner'vanes of the latter, which are yellow; the tail is also slightly 
forked; legs, a pale clay color; bill and eyelids, light blue. The fe- 
male is of a less brilliant yellow, and the streaks of red on the breast 
are fewer and more obscure. Buffon is mistaken in supposing No. 1 
of Pl. enl. plate lviii. to be the female of this species.
