392 INSECTIVOROUS BIRDS. 



bark of vines, and lined with downy vegetable substan- 

 ces. The eggs, 4 to 6, are white, with a reddish tint, 

 and sprinkled with brownish dots at the larger end. As 

 he observed the female sitting so late as the 20th of Au- 

 gust, it is probable they raise two broods in the season. 

 It is very nearly allied to the preceding species, and does 

 not differ from it in size. 



The Autumnal Warbler is from 5^ to 6 inches long, and about 9 in 

 alar stretch. Individuals vary considerably in their color and mark- 

 ings, some being darker above, and more yellow below. The under 

 mandible and legs are yellowish. Audubon's specimens are unusu- 

 ally pale, as well as Wilson's, but I have seen individuals nearly 

 yellow beneath. 



HEMLOCK WARBLER. 



(Sylvia parus, Wilsoiv, v. p. 114. pi. 44. fig. 3. [male.] 



Sp. Charact. — Yellow-olive with black spots ; head above yellow, 

 dotted with black ; line over the eye, sides of the neck, and breast, 

 yellov/ ; wings with 2 broad white bands, and with the tail black ; 

 the 3 lateral tail-feathers white on their inner vanes. 



This very rare species was found by Wilson in the 

 spring, in the Great Pine Swamp in Pennsylvania ; and 

 appeared to take up its residence in the dark hemlock 

 trees* of that desolate region. It was very lively and 

 active, climbing among the branches and hanging from 

 the twigs like a Titmouse. It darted after flies to a 

 considerable distance, and beginning with the lower 

 branches, hunted with regularity upward? to the summit 

 of the tree, and in this way it proceeded very industrious- 

 ly to forage through the forest till satisfied. At intervals, 

 it stopped an instant to warble out a few low and sweet 

 notes, probably for the recognition or company of its 

 mate, which the discoverer, however, did not see.
