The merit of having discovered this bird, is entity 
due to the Peale family, whose exertions have cO* >, 
buted so largely to extend the limits of natural hisW{j 
The male, which he has accurately described f 
figured, was made known to Wilson by the late 
rable Charles Wilson Peale, who alone, and un*'**^ 
accomplished an enterprise, in the formation of ,, 
Philadelphia Museum, that could hardly have %)! 
exceeded under the fostering hand of the most pou'yjj 
government. To the no less zealous researches 0* ; |, 
Titian Peale, the discovery of the female is rect’ 1 ’ f , 
owing, who moreover evinced his sagacity by 
mining its affinities, and pointing out its true ]’. .,1 
in the system. Although it preserves the priDwjj 
characters of the male, yet the difference is sutfici'' 0 
marked to deserve especial notice iu this work. ( ii 
The present specimen was procured on the ham" £ 
the Schuylkill, near Mantua village, on the I s 
August, 1825. It was very active, skipping abo' lt; , c i 
the branches of an oak, attentively searching the l* a jis 
and crevices of the bark, and at intervals takin? jt 
food on the wing, in the manner of the flycatchers- ^ 
warbled in an under tone, not very unlike that o* 
blue-gray flycatcher of Wilson, ( Sylvia carule a, ^ 0 i 
a circumstance that would lead to the suppositm 1 ji 
its being a male in summer dress ; but on dissect* 0 
proved to be a female.
