The Greenlets or Vireos form one of the several 

 leading families of New England birds in numbers of 

 species, others being those of the Thrushes, War- 

 blers, Swallows, and Finches. They are nearly all 

 numerous in individuals, and play no small part in the 

 life of the woods. The White-eye haunts shrubbery, 

 but the rest are sylvan birds of the high forest, the 

 park and orchard. All are summer residents in New 

 England ; all are migratory, insectivorous, and tuneful ; 

 all weave neat cup-like pensile nests, and lay white, 

 finely speckled eggs ; and all share many admirable 

 and agreeable traits of character.
