Warblers. 



Warblers arc among the smallest, most beautiful, and 

 interesting of singing Birds. Many kinds arc generally 

 found in the same locality, and may be seen gliding 

 among the thick foliage, busily engaged in catching 

 minute insects ^\'hich hide beneath the leaves and in 

 the buds and blossoms, and which often escape the 

 sight of other and larger Birds. Some of the Warblers 

 are the sweetest of songsters, as the celebrated Nieht- 

 ingale of Europe, shown in Figure 123. More than 

 fifty kinds are found in the United States ; their very 

 names are beautiful and suggestive. Some of the 

 more common are the Maryland Yellowthroat, the
