Fulvous Whistling-Duck: Origin, Feed, Appearance, And Other Characteristics
Florida, Mexico, Burma, India, California, Louisiana, and Texas are the countries in which fulvous whistling ducks are abundant. It is commonly found worldwide. Southwest Louisiana and southeast Texas are the areas in which they breed. These ducks migrate usually along the Gulf to Mexico. Similarly, a small number of fulvous ducks can be found along the gulf coast in Alabama.
Scientific Name of Fulvous whistling duck is Dendrocygna bicolour. It is also known from some different names like Mexican squealer, squealer, Fulvous tree duck.
Appearance Of Fulvous Whistling-Duck:
A rufous-brown crown is a crown that the adult fulvous whistling ducks wear, irrespective of the gender they all have that crown and upper nape. That upper nape is blackish from the centre of the hindneck. Head, chest, belly, and neck are rufous buff from the sides.

Habitat Of Fulvous Whistling-Duck:
Fulvous whistling duck lives worldwide and can be found approximately in every region of the world. Tropical regions of western and eastern hemispheres are regions in which the inhabits.
While talking about the United States these ducks’ breeds in Louisiana and Texas. They are the resident of the Caribbean and are in some areas of India, Southeast Asia, South America, and Africa.
Shallow wetlands are their favourite areas and if they have long green grass and other vegetation, so they are perfect areas for them to live.
Similarly, freshwater lacks, marshy areas, seasonal freshwater pools, flooded grasslands, and the areas of wet rice cultivation are their areas to live in. If someone wants to see them so they must visit the African Aviary exhibit.
Migrating And Wintering Fulvous Whistling-Duck:
East coast of Mexico is the place for them to winter and leave Louisiana or Texas for winters. The one who breeds in southern California and Arizona, the winter on the west coast of Mexico.
These ducks are widely spread in the world but avoid being in eastern Bolivia, vagrant to Chile, and from the northern Caribbean south to eastern Peru.
How Fulvous Whistling-Duck Lives:
Fulvous whistling ducks are known as the social birds that usually fly in small flocks. During flights and feeding, they are active vocals. During the breeding season, they make pairs and nest themselves in the vicinity where one of two dozen of pairs are also present. In non-breeding seasons they live with the other whistling ducks. There are approximately 8 species of whistling ducks.
They are active in the days and the nights, but their feeding routines are usually done in the early morning after the dawn and before the sunset in the evening.
Aquatic plant seeds are their feed. They usually feed on the surface and prefer to stay in the water in non-feeding hours. As it is obvious from their names, they have loud whistling calls. slow wingbeat and dangling-legs appearance are their characteristics during the flight that most of the whistling ducks have.
Threats To Fulvous Whistling-Duck:
More than 1 million Individuals of Fulvous whistling ducks found in the earth. The host of predators is a regular threat to most of the birds’ faces. More, hunting nowadays is a great threat to them.
In contact with the power lines while flight can also take their lives. They may affect through these threats, but the average population of Fulvous whistling duck remains stable.
Food For Fulvous Whistling-Ducks:
Waste grains, rice, seeds, and structural plant materials are the feed that they used to take in nights. Mostly, invertebrates and the aquatic plant seeds are eaten by the Fulvous Whistling-Ducks. These ducks usually glean to pick the insects from the water as they live in the areas where lots of vegetation is present.
Other than other whistling ducks’, fulvous ducks are filter feeders, they filter out the invertebrates or seeds from the mud or the soil.
In rice fields, most of the farmers take them as the threat to their seeds, as they usually feed on that seeds and collect and eat them while farmers willing to grow rice. Seeds of wheat, green algae, switchgrasses, knur grass, sedges, darnel ryegrass, Colombian wax weed, blue mud plantain, robust marsh wort, sea rag wood. etc. are there feeds.
In invertebrates they eat, small molluscs, dragonfly larvae, water beetles, midges, and earthworms. These invertebrates in small amount are the feed of the adults while the ducks ate a large amount of these invertebrates.
Nesting Of Fulvous Whistling-Duck:
Among Fulvous Whistling-Duck both the male and the female select the nesting spot by landing on the different options for the nesting place. They usually choose to nest on the floating vegetation, grasses,
Both partners construct the base for their nest, where they collect bending stalks. They bend it in the bowl shape and add some dead mesh grass in it.
Ramps are usually present in their nest to reach the water. With the time, when the nest decays and lost its strength they add more material to strengthen it and make it stable. The typical size of the nest is of around 14 inches with a depth of 4.3 inches and the interior bowl of 9.7 inches.
Their breeding mate chose the partner in the spring that remains with them a lifetime. As the rice fields in Lousiana and Texas have low contour leaves and some grown weeds, so female ducks prefer to nest there.
In some cases when there are no rice fields fulvous whistling duck prefers cattails, dense vegetation of cutgrass and other watery plants to make their nest on. Females also construct a nest on the water by using vegetation.
As the duck lays eggs, the nest is formed and continue to lay more eggs. The nest is under constructed so, the eggs usually fell due to the unstable floor in beginning. At a time fulvous whistling duck lays 13 eggs approximately. The incubation period of these eggs is about 26 days.
Both partners incubate the eggs and rear the brood.
Up to 2015, the overall population was increasing of these birds. In South California, the population of fulvous whistling duck is no more to be seen. The only 9 0ut of 20 species are remaining and are at high risk. In some ranges, pesticides caused this decline.
The high conservation threats are due to the destruction of marsh habitats by the development stands and drainage.
This is how such ducks live and survive. people around the world hunt this waterfowl specie. Interestingly they respond to the varying level of water. They mostly change the sites for the sake of breeding and foraging.
