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 farther 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, is marked with a triangular patch 

 of black; the back and hind head is streaked with gray, dusky,
