A plain pale gray warbler, slightly darker above, with distinctive brick-red wing panels and, if seen well, pale gray-green eyes and pinkish legs. Juvenile is washed brownish on the underparts. Pairs and small groups occur in woodland, especially favoring riverine forest and margins of swamps. Gives a loud cheerful duet “chi-weer, chi-weer, chi-weer” and other strident notes that often draw attention to it. Other co-occurring warblers are warmer brown or streaked.
