"Melospiza palustris. Swamp Song Sparrow. Crown bright chestnut, blackening on forehead, the red cap and black vizor as conspicuous as in chipping sparrow; but oftener, crown with obscuremedian ashy line, and streaked with black. An ashy-gray superciliary line; dark brown postocular stripe, bordering the auriculars; sides of head ashy, with grayish-brown auriculars, dusky speckling on cheeks and lores, and slight dusky maxillary spots or streaks. An ashy cervical collar separating the chestnut crown from the back, sometimes pure, oftener interrupted with blackish streaks. The general ash of the sides of head and neck spreads all over the breast and under parts, fading to whitish on throat and belly; the sides, flanks, and crissum marked with brown, and obsoletely streaked with darker brown. Back and rump brown, rather darker than sides of body, boldly variegated with black central streaks of the feathers and their pale brown or grayish edges. Wings so strongly edged with bright bay as to appear almost uniformly brownish-red when closed; but inner secondaries and greater coverts showing some black and whitish besides the bay. Tail likewise strongly edged with bay, and usually showing sharp black shaft lines. Thus well marked by the emphasis of black, bay, and ash." Elliot Coues, 1884
