Synonym.—Formerly included under MARYLAND YELLOW-THROAT. 
Description.—Adult male: A black band or mask on forehead and cheeks, 
bordered on superior margin by a narrow band of ashy white; remaining upper 
parts dull olive-green, brightening on rump, with a brownish cast on crown and 
sometimes on wings and tail; chin, throat, fore breast and crissum bright gamboge 
yellow ; lower breast and belly paler: sides washed with brownish; bill black above, 
light below; feet pale. Adult female: Similar, but without black mask,—grayish 
brown instead; forehead touched with brownish red; much paler yellow below; 
sides of breast and sides more heavily brownish. Male in autumn: Browner above 
and on sides; black mask tipped with grayish; more yellow on belly. Jimmatire 
male: Similar to adult, but browner, and showing only traces of black mask; 
throat paler yellow; chin and breast less pure, inclining to saffron. Under tail- 
coverts yellow at all ages and in all seasons. Length 4.75-5.75 (120.6-146.1) ;

of culmen .43 (10.9). 
Recognition Marks.—Smaller; black facial mask bordered by ashy; yellow

contrast with the uniform yellow of the under parts in G. formosa. 
Nest, sunken in grass tussock or bush clump on or near ground, a bulky but 
neat structure of weed-stalks, bark-strips, leaves of Typha latifolia, grasses, etc., 
carefully lined with grass or hair. Eggs, 4, or 5, white or creamy white, speckled, 
spotted, and sometimes obscurely scrawled, chiefly about larger end, or not, with 
umber or black. Av. size, .70 x .52 (17.8 x 13.2). 
General Range.—Northeastern United States and southeastern British Prov- 
inces, from northern New Jersey, Tennessee and east-central Texas northward; 
south in winter to West Indies and through Mexico to Central America. 
Range in Ohio.—Common summer resident, of universal distribution 
throughout the state, in swamps and lowland thickets.
