BULLETIN OF THE NUTTALL 
ening into yellowish olive-green on the rump and upper tail-coverts, the 
latter having shaft-streaks of reddish-chestnut. Tail-feathers dusky, 
edged externally with yellowish- olive, the inner webs of the two outer 
feathers broadly tipped with white. Wings dusky, all the feathers edged 
with pale brownish-olive, this edging rather widest on the ends of the mid- 
dle and greater coverts, where, however, they do not form any indication 
of bauds. Wing, 2.65 ; tail, 2.50 ; bill, from nostril, .30 ; tarsus, .80. 
The above description will apply almost equally well to the generality of 
bright-colored males in the series, except that the chestnut streaks on the 
upper tail-coverts are not found in any of the others ; there is considerable 
individual variation in the amount of the chestnut on the cheeks, but the 
auriculars seem to be never entirely of this color. 
Adult Female in Spring (No. 63,155, Nat. Mus., Cambridge, Mass. ; H. 
W. Henshaw). Entirely similar to the male, as described above, except 
that the chestnut of the pileum is rather lighter, and less abruptly defined 
posteriorly, the chestnut streaks absent from the upper tail-coverts, no tinge 
of chestnut on the auriculars, which are' plain olive, and size smaller. 
Wing, 2.60 ; tail, 2.40 ; bill, from nostril, .32 ; tarsus, .75. 
A female from Nova Scotia, in breeding dress (parent of eggs in Nat. 
Mus.), is entirely similar in color, but rather smaller in size. Wing, 2.50 ; 
tail, 2.30 ; bill, from nostril, .30 ; tarsus, .75. 
Adult in Autumn (No. 2,567, Mus. R. R., Washington, D. C., October 10, 
1861 ; E. Coues). Generally similar to the spring male, as described 
above, but the chestnut of the pileum overlaid and almost entirely con- 
cealed by olivaceous tips of the feathers ; no tinge of chestnut on the 
auriculars, which are grayish-olive. Yellow beneath as bright and con- 
tinuous as in spring, but chestnut streaks much less distinct. Markings 
generally less distinct, and colors more suffused ; tips of wing-coverts and 
edges of tertials decidedly brownish. 
A specimen from Carlisle, Penn., in the same plumage (No. 783, Mus. 
S. F. Baird, October 7, 1842), differs merely in being more brownish above. 
The measurements of this and the preceding may be found in the accom- 
panying table. 
Adult in Winter (No. 59,811, Nat. Mus., Hibernia, Florida, February, 
1870 ; G. A. Boardman). Similar to the autumnal plumage, but less 
brownish above. 
Young, first Plumage (No. 2,807, Mus. R. R., St. Croix R., Maine, July 
20, 1874 ; G. A. Boardman). Above grayish-brown, distinctly streaked 
with dusky, the streaks broader on the back, where they widen at the end 
of the feathers ; both rows of wing-coverts narrowly’tipped with pale buff ; 
tertials edged externally with rusty cinnamon ; rump and outer edges of 
primaries and rectrices yellowish olive-green ; upper tail-coverts pale rusty- 
cinnamon. Lower parts mostly dull whitish, tinged on the throat and 
abdomen with lemon-yellow, the throat, breast, and sides heavily streaked 
with dusky ; crissum and edge of the wing bright yellow.
