42 AVIFAUNA COLUMBIANA. 



August 25 to the second week in October. At any season it inhabits 

 high open woods, and is usually seen in the tops of the trees or at the 

 ends of the branches, scrambling, skipping, and fluttering with inces- 

 sant activity on the tufts of leaves and blossoms. One which we pro- 

 cured was a partial albino, singularly variegated with pure white in 

 patches amidst its normal markings. [93] 



29. ('«■).) Protonotaria citrea (Bodd.) Bd. Prothonotary Warbler. 

 Extremely rare; apparently only an accidental visitor. It ought, 



however, to be regularly found here, even if rarely, as it goes north to 

 New England. We have not learned of more than one occurrence, that 

 of an individual seen by ourselves in a swampy briar patch, May 2, 

 1861. [95 1 



30. (60.) Helmintherus vermivorus (Gm.) Bp. Worm-eating Warbler. 



A rather uncommon summer resident, breeding sparingly. TVe used 

 to shoot it at any time during the summer, particularly in the wooded 

 ravines along Rock Creek, and did not consider it rare, though we doubt- 

 less often overlooked it, owing to its close general resemblance to Slu- 

 ms auricapillus, which was extremely abundant in the same places. It 

 is slow and sedate in its movements, and is often seen rambling over

the ground, whence, when disturbed, it flies to some low branch of a tree, 

 much after the manner of the species just named. Of late years sev- 

 eral nests have been taken, one that we know of by Mr. Jouy, and an- 

 other by Mr. Palmer, the taxidermist of the Smithsonian. The bird 

 arrives the first week in May, and remains until the third week in Sep- 

 tember. [90J 



31. (*>2.) Helminthophila pinus (Linn.) Bd. Blue-winged Yellow Warbler. 

 Spring and autumn migrant; very rare. Found on wooded hillsides 



and in tangled thickets. [98] 



32. (61.) Helminthophila chrysoptera (Linn.) lid. Golden-winged Warbler. 

 Spring and autumn migrant. Found in the tops of large trees in 



open woods; maybe recognized from its habit of hanging head and 

 back downward, when the golden wing-bars become prominent. [192] 



33. (63.) Helminthophila ruficapilla ( Wils.) Bd. Nashville Warbler. 

 Spring and autumn migrant; rare. It was, however, not uncommon 



in the spring of 1882. [19G] 



34. (04.) Helminthophila peregrina (Wils.) Cah. Tennessee Warbler. 

 Spring and autumn migrant; very rare. Mr. William Palmer informs 



us of one he shot at Arlington, September 28, 1882. [199]
