and have probably never met with it. Indeed, it is so seldom 

 seen in this part of Pennsylvania, that few even of our own 

 writers have mentioned it. 



I lately received a very neat drawing of this bird, done by 

 a young lady in Middleton, Connecticut, where it seems also 

 to be a rare species.

Of this bird I can give but little account. It is one of those 

 transient visitors that pass through Pennsylvania in April and 

 May, on their way further north to breed. During its stay 

 here, which seldom exceeds a week or ten days, it appears 

 actively engaged among the opening buds and young leaves, 

 in search of insects ; has no song but a feeble chirp, or 

 twitter ; and is not numerous. As it leaves us early in May, 

 it probably breeds in Canada, or perhaps some parts of New 

 England, though I have no certain knowledge of the fact. 

 In a whole day's excursion it is rare to meet with more than 

 one or two of these birds, though a thousand individuals of 

 some species may be seen in the same time. Perhaps they 

 may be more numerous on some other part of the continent. 



The length of this species is five inches ; the extent, seven 

 and three-quarters. The front, line over the eye, and ear- 

 feathers, are pure white ; upper part of the head, brilliant 

 yellow ; the lores and space immediately below are marked 

 with a triangular patch of black ; the back and hind head are
