90 LAND-BIRDS. 



more than three feet high " ; another " was built within a 

 brace-hole in a mill " ; and a third " in a hollow snag, about 

 five feet from the ground, in the river bottom." The eggs 

 average .68 X .55 of an inch, and are cream white, with lilac, 

 purplish brown (and black) markings. 



c. The Prothonotary Warblers have little or no right to be 

 included in the list of the birds of Massachusetts, and I have 

 never seen them here (unless perhaps once a pair, at dark in 

 October). They prefer the borders of streams, and neigh- 

 borhood of water, to drier ground, and swampy thickets to 

 the woods and forests. Otherwise, their habits are essentially 

 like those of the Worm-eating Warbler and other allied species. 



d. Their ordinary note is said to be like the feeble tsip of 

 the White-throated Sparrow, but of more characteristic notes 

 I know nothing.* The " Prothonotaries " strongly resemble 

 the Blue-winged Yellow Warblers, who are much more likely 

 to occur in southern New England, and therefore should an 

 inexperienced student meet either in his rambles through this 

 State, let him carefully note which it is. 



VI. HELMINTHOPHILA. 



A. PINUS. Blue-winged Yellow Warbler. No one, I be- 

 lieve, has reported the presence of this bird in New England, 

 except Mr. Samuels, f ,

 blotches, white (or nearly so), and eye-stripe, or lore, black.
