THE iiiUDS OF Xi:\V JEUSKY. 263 



Family MNIOTILTID^. 



The AVooi) Warblers. 



A large family of small, generally brightly colored birds, mostly 

 arboreal, some terrestrial or living among the bushes. Almost entirely 

 insectivorous, with slender sharp pointed bills. The songs of most of 

 the species are weak and lisping, tliough some are much stronger and 

 melodious. 



These little birds form the bulk of the great night flights of the 

 spring and fall migrations. A few are familiar summer residents, but 

 the majority spend the breeding season in the depths of the northern 

 woodland and forests. On their migration in May and September, 

 however, they are always conspicuous, thronging the tree-tops as they 

 search for food.
