The Chestnut-sided Warbler is a warbler of second-growth forests and shrubby edges, recognized by its yellow cap, white face, and chestnut-red streaks along the sides. It was extremely rare in Audubon's era when old-growth dominated the landscape; it has actually benefited from forest fragmentation and is now one of the more common warblers in the Northeast. Males hold their tails cocked upward like a wren.
