This is another nondescript, first met with in 
Great Pine swamp, Pennsylvania. From observio? i 
almost alu'ays among the branches of the heinl^f, 
trees, 1 have designated it by that appellation, 
markings of its plumage not affording me a pecnKa **3 
sufficient for a specific name. It is a most lively 
active little bird, climbing among the twigs, and hang’f'j 
like a titmouse on the branches ; but possessing all ^ 
external characters of the warblers. It has a fen' j I 
and very sweet notes, at which times it stops 
repeats them for a short time, then darts abou* . I 
before. It shoots after flies to a considerable distaO^A 
often begins at the lower branches, and hunts * 
great regularity and admirable dexterity, upwards ’ 
the top, then flies oflF to the next tree, at the lo" , 
branches of which it commences huntino* uuwards 
before. ” ^ ^ |
