YELLOW-THROATED WARBLER. 229 



suspended to a kind of rope which hangs from tree to tree, 

 usually depending from branches that bend over rivers or 

 ravines. The nest itself is made of dry blades of grass, the 

 ribs of leaves, and slender root-fibres, the whole interwoven 

 together with great art ; it is also fastened to, or rather worked 

 into, the pendant strings made of the tough silky fibres of some 

 species of Echitcs, or other plant of that family. It is, in fact, 

 a small circular bed, so thick and compact as to exclude the 

 rain, left to rock in the wind without sustaining or being ac- 

 cessible to any injury. The more securely to defend this 

 precious habitation from the attacks of numerous enemies, the 

 opening, or entrance, is neither made on the top nor the side, 

 but at the bottom ; nor is the access direct, for after passing 

 the vestibule, it is necessary to go over a kind of partition, and 

 through another aperture, before it descends into the guarded 

 abode of its eggs and young. This interior lodgment is round 

 and soft, being lined with a kind of lichen, or the silky down 

 of plants. 



This species is confined chiefly to the South Atlantic States, 

 though occasionally a few wander to New York, Connecticut, 

 and Massachusetts. 



Note. — The Sycamore Warbler (Z?. dominica albilora) 

 differs from the type in being smaller (length 4_j4 to 5j'^ inches) 

 and in having the line over the eyes whife, instead of yellow. It 

 occurs along- the Mississippi valley and eastward to Ohio, where 

 it is common. It has been taken also in South Carolina and 

 Florida.
