SONG-BIRDS. Warblers 



The Creeper, when at rest, is not at all graceful, but it is 

 most interesting to watch its zig-zag course from the tree 

 trunk out to the angles of the crooked branches, picking up 

 insects which are invisible to us, with its slender, sharp bill. 

 In watching the manoeuvres of all bark-feeding birds, you 

 must keep in mind that the eyes of birds are powerful mag- 

 nifiers, and that to them objects appear twenty-five times as 

 large as they do to us. 



Worm-eating Warbler: Helmitherus vermivorus. 



Length: 5.50 inches. 



Male and Female : Head yellowish brown, black stripe on each side 



of crown, also back of eye. Above greenish olive. Under parts 



buffy. Bill and feet light. 

 Song: Similar to that of Chipping Sparrow, — "trrrr-rrr-rrr," — 



from which Mr. Ridgway says that "it is difficult sometimes 



for the most critical listener to distinguish it." 

 Season : Bare summer resident in southern New England. 

 Breeds : In all parts of its United States range, but casually in the 



northerly sections. 

 Nest : On the ground in woods, and in swamp tussocks, or in a ground 



hollow like the Ovenbirds, and composed chiefly of leaves. 

 Eggs : 4-5, clear white, specked with reddish brown. 

 Eange: Eastern United States, north to southern New York and 



southern New England, west to eastern Nebraska and Texas, 



south, in winter, to Cuba and Central America. 



This compact, soberly clad Warbler is not at all common 

 north of New Jersey, and, even where it is plentiful, it is 

 very likely to escape notice ; for its colouring is such as to 

 make it blend with the ground upon which it nests, or with 

 the branches and trunks of trees where it frequently creeps 

 and circles in feeding, after the manner of the Brown 

 Creeper. Its nest seems also to be well concealed, and 

 generally in remote places, for the descriptions of it are 

 infrequent.
