SYLVIA CASTAXEA.

WILSON, PLATE XIV. FIG. IT. 
This very rare species passes through Pennsyl''*®!; 
about the beginning of May, and soon disappears. I*."!; 
many of tlie habits of tlie titmouse, and all their actit’f? 
hanging among the extremities of the twigs, and diU'*’'^ 
about from place to place, with restless diligence’ll 
search of various kinds of the larvae of insects* .p 
is never seen here in summer, and v’ery rarely nP ^^*1 
return, owing, no doubt, to the greater abundaiice.p | 
foliage at that time, and to the silence and real scat'll 
of the species. Of its nest and cga-, we are altog®’^ 
uninformed. 
The length of this bird is five inches, breadth, elef'^p 
throat, breast, and sides under the wings, pale chcstP';^ 
or hay ; forehead, cheeks, line over, and strip 
the eye, black ; crown, deep chestnut ; lower partSi .a 
yellowish white ; hind head and back, streaked "ij 
black, on a grayish biiti' ground ; wings, bro"’'^ 
black, crossed wdth two bars of white ; tail, fot'^ij 
hrow-nish black, edged with ash, the three e.xtC^y 
feathers marked with a spot of white 011 their 
edges; behind the eye is a broad oblong spo‘wl 
yellowish white. The female has much less otLl 
bay colour on the breast ; the black on the forchepPj, 
also less, and of a brownish tint. The legs and fcp\,l 
both, are dark ash, the claws, extremely sharp 1 
climbing and hanging; the bill is black; irides, hpAj. 
The ornithologists of Europe take no notice of U 
species, and have probably never met with it. I® 
it is so seldom seen in this part of Pennsylvania! 
few even of onr ow'n w'riters have mentioned it. . -J, 
I lately received a very neat drawing of this >’ a 
done by a young lady in Middleton, Connecticut, 
it seems also to be a rare species.
