Abstract

A breeding population of fulvous whistling-ducks (Dendrocygna bicolor) has become established in south Florida, representing an increase in Florida's resident waterfowl resource. This population is centered in the Everglades Agricultural Area (EAA), and is closely associated with rice culture, which provides nesting, brood-rearing, and feeding habitat. During fall and winter, ducks move to natural marshes throughout the southern half of the state; however, an unknown percentage migrate to Cuba. Fulvous whistling-ducks rely primarily on rice seeds when occupying EAA rice fields, and seeds of emergent aquatic plants are important foods in the spring. Development of an accurate census or index, and studies on the reproductive ecology of fulvous whistling-ducks in Florida are priority management needs.
