Warbling Vireo. 207 



the yellow-throated vireo, is rarely seen in this region 

 away from the tangled woods and thickets of the river 

 bottoms, and hence the resident of upland districts need 

 not mistake any of its congeners for this regular wood- 

 land species. Two others of the group, the white-eyed 

 and Bell's vireos, inhabit the thickets and tangles of 

 upland localities, hanging their nests in the forks of 

 drooping twigs among low bushes and shrubbery, and 

 confining their movements to the immediate vicinity of 

 their resorts. They rarely appear above the tops of their 

 lowly haunts, so they need not be confounded with the 

 subject of this sketch and the remaining species. The 

 red-eyed and the warbling vireos, however, are likely to 

 be confused; yet theit* calls and notes of alarm and their 

 noticeable songs are so diiferent that the discriminating 

 student can identify with accuracy each of them by giv- 

 ing ordinary attention to the characteristics mentioned in 

 the descriptions of the two species. As a further aid in 

 discriminating between the two species, the red-eyed vireo 

 comes to us several days earlier than the warbling vireo, 

 giving us a little time to obtain at least an introduction to 

 it before the latter announces its presence. 



The warbling vireo is found throughout North America 

 in general, from the Gulf of Mexico to the so-called Fur 

 Countries, though the representatives of the species which 

 live in western regions are said to have plainer colors and 

 are hence classed as a separate race by some authorities. 

 It breeds throughout its extensive habitat, and probably 

 winters in the Gulf regions. The first individuals of the 

 species come among us in the fourth week of April, not 

 many days after the red-eyed vireo has delivered his first 

 exhortations, and add their touching carols to the rapidly 

 increasing chorals of nature. They commonly appear in 

 the same week with two other noted friends of the high- 

 way, the rose-breasted grosbeak and the Baltimore oriole, 

 and thenceforth the maples and elms are melodious with 

 the notes of the three of our most gifted songsters. Unlike 

 the two species named, however, the warbling vireos do 

 not tire of their efforts to cheer us with their music so 

 early in the season. Their notes are heard almost daily 

 along the streets of village, town, and city, from the
