The males of this species are distinguished from those of the Red-wings by the absence of light margins to the orange red shoulders. They are fairly abundant in their restricted localities, building their nests in swamps about ponds and streams. The nests are like those of the Red-wings, and the eggs are similar and with the same great variations in markings, but average a trifle smaller; size .05 x .67.
Dull bluish white.
