Like a mix between Gray-crowned and Olive-crowned Yellowthroats, this species combines a full black mask with a gray crown. Underparts are entirely yellow, back is olive. Female is similar to other yellowthroats but note her grayish cheeks and lack of contrastingly dark lores. Found singly or in pairs in wet weedy fields and marshes. Listen for the sweet whistled song. Tends to stay low, but males perch higher when singing.
