Fulvous Whistling-Duck - Ross Feldner

This stocky duck’s name comes from its tawny coloration (fulvous) and its whistling call. Perfect naming except for the standout blue legs and feet.

Once known as the Fulvous Tree Duck, this is one of the most widely spread waterfowl in the world. These ducks consume a diet rich in aquatic plant seeds; such as rice seeds and aquatic invertebrates whilte dabbling at or below the water level.

They usually nest on dikes, rafts, flooded fields and levees with the nest constructed of nearby vegetation formed into a bowl lined with grass. Females lay a large clutch of 12-13 eggs with both males and females caring for the offspring.

Fulvous Whistling-Ducks are well known for their tendency to travel hundreds of miles in roving flocks in search of food and are very social birds that flock together in small family groups chattering to each other while feeding and in flight.

Fun Facts

Like an avian sieve most of their foraging is by filter-feeding—straining through fine mud for seeds and invertebrates.

Pesticides applied in the 1960s to rice caused serious declines in Texas and Louisiana populations. Since then their populations have stabilized.

Fulvous Whistling-Ducks only started breeding in the U.S. in the late 19th and early 20th centuries, following the beginning of rice farming.

They usually feed both day and night.

Sometimes more than one duck will use the same nest.

The gray colored ducklings leave the nest within a day of hatching.

They display their aggression when threatened by throwing back their heads. Before taking off in alarm, they often shake their head sideways.
