In alternate plumage, the only other warbler with rusty sides is the bay
breasted warbler but it has a brown, not yellow, crown and has a dark
throat. In basic (fall) and immature plumages the yellow wing bars can
also be found in the golden-winged warbler but this species has a dark
throat and cheek patch. The white eye ring, unstreaked underparts, and
gray face are also good field marks.
