confidence in man, permitting near approaches 

 without the least fear. 



It is extremely agile in its movements, and like 

 its congeners, combines many of the traits of the 

 Ccrthiidte and Paridce, in a remarkable degree; 

 superadded to which, is the possession of many of 

 the attributes of the Muscicapidtf, being able to 

 capture insects upon the wing, with nearly the 

 adroitness of the members of this family. Being 

 less erratic than most of its kindred, it remains 

 for long periods gleaning among the foliage of the 

 same tree. 



Not unlike the Bay-breasted Warbler, this 

 species certainly reserves its powers of song until 

 it has attained its northern quarters. Not so much 

 as a single note has it been heard to utter. Its 

 departure usually occurs about the 22nd of Ma)', 

 making the length of its stay nearly three weeks. 



Divers kinds of insects constitute its dietary. 

 We have detected remains ot the following in the 

 stomachs of several individuals: Rhynchanus 

 strobi, Chrysomela ccsruleipennis, CrafonycJtns, cine- 

 reus, Harpalus compar, Platynus citpripennis, among 

 beetles ; Musca domestica, Tabanus lincola, Syrphns 

 obscurus, among diptera , besides Aphis wait, For- 

 mica sangninca, earthworms and a single species 

 of cut-worm. The results of these examinations 

 conduct to the conclusion, that in habits it is n,ot 

 strictly arboreal, but occasionally terrestrial. 



This species was formerly regarded as rather 

 rare by our older ornithological writers. Wilson
