Tiie Gohlen-wing is a eh)se ally of the Bhie-winged Warbler wliich 

 it resembles in liabits. Mr. Thurbei' calls it a rare summer resident 

 at Morristown. and Mr. P. B. Philipp has found it nesting at Newton, 

 Sussex county. J)r. Dwight and Mr. Ehoads found it at Lake Hopat- 

 cong in summer and regard it as a breeder there, and in June, 1909, 

 Mr. Rhoads found it at various points in northern Passaic and Sussex 

 counties. 



This species and the Bhu'-winged Warhler are supposed to hyl)ridize, 

 as (inly in this way can we account for the curious birds known as 

 Brew^teiV ami Lawrence's Waiblers which are inteimediate between 

 thenj. 



Vermivora leucobronchialis (Brewster). 



Brewster's Warbler. 

 Vermivora leucobronchialis (Brewster). 



I^awrence's Warbler. 



These birds arc now generally recognized as hybrids, between the Blue- 

 winged and (JoliUn-winged Warblers. Brewster's Warbler is essentially a 

 (iolden-wing without the black throat, while Lawrence's Warbler is a Blue- 

 wing with a black tliroat, but various intermediate forms have also been ob- 

 tained.
