Mexico (Grayson); Guatemala (Salvin); Cuba (Gundl.) ; Jamaica (March); St. Thomas (Newton); Trinidad (Leotaud). The American Widgeon is said to be very common in Cuba during the annual migration from September to April. In Jamaica, too, it is to be seen in all its forms and variety of plumage. Mr. Riise procured specimens in St. Thomas; and Le'otaud records it as a regular winter visitant to Trinidad. In Central America it likewise occurs in winter, having been found by Salvin in all the Guatemalan lakes during that season. 2. MARECA SIBILATRIX. Anas sibilatrix, Poeppig, Fror.
