Underparts were bright yellow on throat, diffusing to paler yellow on lower breast and lower flanks; belly and vent were white; a couple of pale gray streaks were evident on the side of the breast, with a couple of darker gray streaks on the flanks. Undertail was black on the basal half and white on the apical half. Legs were black.

Similar Species Discussion
No other North American bird has the combination of features of this bird. In particulaar, the tail pattern is unique. Nashville Warbler has a gray head with white eye ring and bright yellow throat but lacks wingbars. Northern Parula has wingbars and yellow breast but lack streaks on back and sides and complete eyering. Many other warblers share one or two field marks.
I have banded basic plumage Magnolia Warblers in Guatemala, and observed many.
