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

 transient visitors that pass thro 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 per- 

 haps some parts of New England ; tho 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 ; tho 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 grey, dusky, black 

 and dull yellow; wings black, primaries edged with pale blue, the 

 first and second iwv of coverts broadly tipt with pale yellow, se- 

 condaries broadly edged with the same; tail black, handsomely 

 forked, exteriorly edged with ash^ the inner webs of the three ex- 

 terior feathers with each a spot of white; from the extremity of
