Jieinarkg. — The only variation of note in tlie plumage of otherwise typical 

 specimens of this species occurs in the color of the wing-bars, which in some 

 specimens are tingetl with yellow. A specimen in Mr. Brewster's collection 

 (No. 25,.511, Seymour, Conn., June 11, 188!», E. A. Eames; shows this variation 

 carried to an extreme, and lias the wing-burs us broadly yellow lus in //. ehrys- 

 o/)/<';'«, thougii in every other respect it is typical pi huh. Between this spe- 

 cies and If. chryxoptira there exists a comidcte set of iiitiTgradcs, which are 

 variously called //. leucobroiichia/in and //. lawn ucei. They are generally 

 considered to be liybrids, and it has also been suggested that ilichromatism 

 may aid in producing their coloration. Tlieir relationships will bo found dis- 

 cus.scd under the following references: Bn^wstcr, Bull. Nutt. Orn. Club, vi,

Nest., of bark and leaves, lined witli fine strips of bark and tendrils, and 

 firmly wrapped with numerous leaves, wlio.>*e stems point upward, on the 

 ground, generally in or at the border of second growth. Kijgx, four to si: 

 white, thinly speckled with rufous, cinnamon-brown, or rufous-l>rown,

This species may be found in scrubby second growths, woodland 

 borders, or even the lower trees of dense woods. Its movements are 

 rather slow and leisurely, and, like a Chickadee, it nuiy sometimes bo 

 seen hanging head downward while searching for food. 



It is at times a rather persistent songster, and its peculiar song is 

 not likely to be mistaken for that of any other Warbler. As a rule, 

 it consists of the two drawled, whee/y notes siiri'-rficc : the first inhaled, 

 the second exhaled. A less common song, uttered later in the season, 

 is tcee, vM-chl-chl-ehi, chilr, chi'e-chur, and is sometimes accompanied 

 by peculiar kik notes.
