and composed of various kinds of material, such as leaves, pieces 

 of wasps' nests, strips of bark, etc. The inner lining is com- 

 posed of fine strips of the bark of the grape-vine and the stems 

 of grasses. It has been stated that hair is used in this lining, 

 but the writer has never met with it in his observations. The 

 eggs are pure white, irregularly marked near the thicker end 

 with small dark brown specks. In a set of four eggs, three were 

 observed to have a few dots near the smaller end, which were 

 missing from the fourth. This set was taken in the second week 

 of June. 



t Vireo noveboracensis (Gmel.). White-eyed Vireo. 



This species makes its appearance about the same time as the 

 red-eyed vireo, to which it is closely related. The writer has 

 observed it in the fall, not quite as late as the former. Its ways 

 are a little more vivacious and sprightly, but it frequents nearly 

 the same localities, and its nidification is not essentially dif- 

 ferent, while its notes are quite distinct from those of that species. 

 It seems to be quite common in this region, but less abundant 

 than the red -eyed vireo. 



Vireo flavifrons (Viell.). Yellow-throated Vireo. 



During the period of migration this species is not so abundant 

 as the two preceding ones, and in summer the difference in num- 

 bers is much greater. It frequents the medium-sized and large 

 trees of woods in company with birds of its own kind, but some- 

 times with other vireos. The notes are rather weak, not nearly 

 so loud and vivacious as those of the two preceding vireos, and 

 show a marked difference in that respect. It arrives in this 

 vicinity during the latter part of April and leaves toward the 

 close of September. 



Ampelis cedrorum (Viell.). Cedar Waxwing. 



This well-known species, commonly called by the farmer 

 Cedar Lark, may be observed from early in March throughout 

 the summer until the early part of December, but varies greatly
