VIREOSYLVIA OLIYACEUS, Bonaparte. 
Red-eyed Vireo. 
The Red-eyed Vireo is quite an abundant species tliroughout East- 
ern North America, ranging from Florida in a northeasterly direction to 
Nova Scotia, thence northwesterly to Lake Winnipeg and Washington 
Territory, and westerly to Ogden, Utah. Accidental specimens have been 
procured in Greenland and England, but never more than a single indi- 
vidual in each locality. 
Many of these birds winter in Florida, and as sjiecimens have been 
met with in Central America, Cuba, Trinidad, and on the Isthmus of 
Panama, it is highly probable that many betake themselves thither when 
the period of breeding is over in their northern homes. 
Early in March the latter enter the United States, possibly by way 
of Texas and Florida, and wend their movements northward, reaching the 
Middle States late in April; the New England, about the middle of May; 
and the extreme northwest, a fortnight later. 
Like all of its peculiar and characteristic genus, this species affects a 
fondness for forests, or the summits of tall trees, but seldom ventures 
upon the ground. It is, however, not wholly sylvan. At times it may be 
found around dwellings, or along the shaded streets of rural towns, in 
quest of the various insects which contribute to its sustenance. 
As it gleans among the tree-tops, the simple, pleasing and musical 
notes of the male may be heard at somewhat regular intervals. So unsus- 
picious and familiar is he then, that passers-by may come and go, and 
their presence be unheeded.
