The diet of the Fulvous Whistling Duck
The Fulvous Whistling Duck is primarily herbivorous, but it may consume some small insects, with seeds comprising the majority of its diet. Its diet consists of over 95% plant-based materials, primarily seeds of plants and aquatic grasses, including paspalum, wild rice, as well as smartweeds, among others.
Additionally, this duck also consumes a small number of aquatic insects.
The life cycle of the Fulvous Whistling Duck
- The life cycle of the Fulvous Whistling Duck begins from an egg, like most birds. A female Fulvous Whistling Duck typically lays 12-14 white eggs, which become spotted in the nest. Females may lay eggs in communal nests, which can contain “dump nests” with more than 60 eggs.
- The incubation period ranges from 24 to 26 days, and eggs may be left unattended for hours on warm days until hatching approaches.
- Ducklings are proficient swimmers and divers, cared for by their parents but also capable of finding food on their own. They start growing small feathers at around two months old.
- Once mature, Fulvous Whistling Ducks may mate for life. During courtship, pairs or groups of ducks may fly in large circles with twisting and turning. Nests are typically located on the ground near water or directly above water in dense marshes. The nests are woven from grass, sedges, and rushes, without any added down feathers like many other waterfowl.
- Fulvous Whistling Ducks are social birds, gathering in small family groups. They are active both day and night but do most of their feeding in the early hours after dawn or in the evening before sunset.
Migration and Wintering of Fulvous Whistling Ducks
- Most Fulvous Whistling Ducks leave Louisiana and Texas in the fall and spend the winter along the eastern coast of Mexico.
- It’s assumed that the smaller populations breeding in southern California and Arizona winter along the western coast of Mexico, while those in Florida are non-migratory. In newer tropical areas, Fulvous Whistling Ducks are widely distributed, but they are generally rare from northern Caribbean southwards to eastern Peru, eastern Bolivia, and northern Argentina.
