Sp. Co.—Male.—Bill black ; feet pale yellow. Head and neck all round and fore part of the breast black. A broad patch 
on the forehead extending round on the entire cheeks and ear coverts, with the under parts bright yellow. Upper parts and 
sides of the body olive green. Greater portion of inner web of three outer tail feathers white. 
Female similar ; the crown like the back ; the forehead yellowish ; the sides of the head yellow, tinged with olive on the 
lores and ear coverts. 
Length, 5; wing, 2.75; tail, 2.55. (Skin.) 
Hab.—Eastern United States to the Missouri; south to Guatemala. 
The bill, though sylvicoline, is broad at the base and depressed, with prominent bristles. 
The wings are long and pointed, though the first primary is nearly .15 shorter than the second 
or longest. The tail is slightly graduated. 
An immature male differs from that described above by having the black of the head restricted 
to a margin of the yellow on the top and sides, and a faint indication of the same on the throat. 
As a general thing the yellow of the under coverts is not so intense as that of the belly, and 
the feathers of the lores are tipped with black. The width of the yellow forehead varies, being 
sometimes nearly equal to the black, sometimes one-half only.
