Color. Adult male in spring. Abo.ve. slaty blue, brightest on the crown, tinged with ashv on nape 

 and back. Concealed centers of the feathers on top of head, dusky. Middle of back and scapularies, broadly 

 streaked with black, and the feathers of these parts are margined with rufous. The ujiper tail coverts show 

 small streaks of black. Wings, including u]>per coverts, dark brown, becoming lighter on the inner webs of 

 the feathers, which are all edged with ashy white, pui'est on the tertiaries, but elsewhere tinged with rufous. 

 Greater coverts tipped with white, forming a bar. Tail, dark brown, with the outer web of outer feathers 

 narrowly margined with white, and with all the outer webs of the other feathers edged with ashy. There is 

 11 spot of white on the inner web of outer feather, about .80 long, which extends along the vein for .40, then 

 runs acutely to the tip of the feather. The upper margin of the spot runs, obliquely from the vein to near 

 the margin, then turns abruptly upward, along the edge for a short distance. A spot on the second feather 

 is much the same form, but does not quite touch the vein anywhere, and is only about .(iO long. There is a 

 mere dot on the third feather at the tip. Beneath, pure yellow, but rather pale, lighter than the same color 

 on the Yellow-throated Warbler, with tlie sides distinctly streaked with a chmble row of black spots, the 

 upper of which begins at the lower corner of the black patch on ear coverts, the breast being unspotted. 

 Under wing and tail coverts, white, the latter very slightly tinged with yellowish. Narrow frontal line, 

 loral region, narrow line o>er eye, extending behind it, then broadening out on the ear coverts, black, with 

 ear coverts slightly tipped and margined with ashy. Elongated patch on upper and lower eyelid, white. 

 Iris, brown. Bill, brown, lighter at base of lower mandible. Feet, dark brown, soles, yellow. 



Adult female in si)rlng, similar, but the blue of the head shows the dark lines more distinctly, and the 

 s\shy of the nape is more tinged with rufous as are the upper jiarts, excepting the rump and upper tail cov- 

 erts, which are like those of the male. The white banil on wing is replaced by one of ashy. The white on 

 the tail is not as extended, and there is no indication of any spot on the third feather. Beneath, paler yel- 

 low than in the male : the sides are tinged with rufous; the dark markings are not as distinct, and the black 

 of the sides of the head is not quite as well developed. The bill is very pale, the light portions of the under 

 mandible being more extended Adult male in autumn, similar to the spring plumage in general markings, 

 but the entire upper parts are overwashed with rufous, and ihis tinting extends down on the ear coverts. 

 The colors beneath are paler, especially on the chin and upper breast, while the under tail coverts are more 

 slightly tinged with yellow. Adult female in autumn, diflers from the spring plumage in being even more 

 strongly tinged with rufous above, the blue of the head being usually obscured with it, while the white wing 

 bar is wanting. The under parts are quite pale, but the under tail coverts are very yellow, and show black 

 shaft streaks on the ti]»s. Y'oung males of the second year, above, have much of the colors of the adult fe- 

 male, and is similar beneath, being pale 3'ellow, but the upper breast is crossed by a wide band of indistinct 

 spots of dusky, and the streakings on the sides are narrower. The white on the second tail feather is re- 

 placed by a small spot. Females of this age are even duller, with the spot on the second tail feather reduced 

 to a round dot. 



Y'oung males of the year, in winter, have the black of the back wholly obscured with ashy rufous, espec- 

 ially on the upper tail coverts, where the black shaft lines are quite prominent. The black Unes on the back
