Dr. Thomas Barbour (1943) speaks of it thus in Cuba: "Common in woods and thickets. A few arrive in August, and by September they are very abundant, especially in the overgrown jungles about the Ciénaga." Edward S. Dingle (MS.) has sent to A. C. Bent a remarkable winter record of a black-and-white warbler seen on Middleburg plantation, Huger, S. C., on January 13, 1944.
