210 NORTH AMERICAN BIRDS. 



A true Warbler in most of its attributes, this bird has many of the liabits of 

 Titmice. Like these it frequents the tops of tlie taller trees, feeding on the 

 small winged insects and caterj)illars that abound among the young leaves 

 and blossoms. It has no song, properly so called, its notes are feeble and 

 few, and can be heard only a short distance. 



The song of this species is said by Mr. Trippe, of Orange, N. Y., to 

 be a somewhat sharp and lisping, yet quite varied and pleasing, series of 

 notes. 



Mr. Audubon speaks of this species as breeding in Louisiana, but his 

 description of the nest differs so entirely from such as are met with in Mas- 

 sachusetts as to suggest doubts as to the correctness of the identification. 

 He describes them as flitting over damp places, the edges of ponds and 

 streams, and pursuing their prey with great activity. Tliey resort to the 

 woods as soon as the foliage appears on the forest trees, and glean among tlie 

 leaves for tlie smaller winged insects. 



The nests of this Warbler, so far as has fallen under my observation, have 

 always been made of long gray lichens still attached to the trees on whicli 

 they grow. With great skill do these tiny architects gather up, fasten 

 together, and interweave, one with the other, the hanging ends and longer 

 branches. By an elaborate intertwining of these long fibres they Ibrm tlie 

 principal part, sometimes the whole, of their nests. These structures are at 

 once simple, beautiful, ingenious, and skilfully wrought. AVhen first made,' 

 they are somewhat rude and iinfinished, but as their family are gathered, 

 the eggs deposited, incubated, and hatched, a change has been going on. Lit- 

 tle by little has the male bird busied himself, when not procuring food for 

 his mate, in improving, strengthening, and enlarging the nest. These same 

 acts of improvement upon the original nests are noticed with Humming- 

 Birds, Vireos, and a few other birds. 



The nests are sometimes constructed on the sides of trunks of trees, when 

 covered with the long gray lichens, but are more frequently found hanging 

 from branches usually not more than six or eight feet from the ground. 

 Thus surrounded by long hanging mosses in clumps not distinguishable from 

 the nests themselves, they would not be readily recognized were it not that 

 those familiar with the habits of the bird may be readily guided to the spot 

 by the artless movements of the unsuspecting jiarents. 



These birds are confiding, easily approached, and rarely exhibit any signs of 

 alarm. Even when their nest is disturbed they make but little complaint, and 

 do not manifest any very great signs of emotion. When built against a trunk 

 these nests consist only of an interweaving of the moss above and below a 

 very small opening, within which a small cup-shaped flooring has been made 

 of the same material, and usually cannot be removed without destroying all 

 semblance of a nest. When pensile they are imperfectly circular in shape, 

 with an entrance on one side, and rarely with any lining. Occasionally they 

 are models of symmetry and beauty.
