Listen for their high-pitched whistles as they travel from feeding fields to roosting sites.

About 80,000 birds are generally counted along the east and west coasts of Mexico each winter, and researchers estimate a breeding population of several thousand in southern Texas. Listen for them, too—these ducks really do have a whistle for their call. In some areas (such as coastal Texas), feeding of this species has become popular, with landowners tossing out corn near ponds to attract hundreds of whistling-ducks. Significant breeding populations also exist in Mexico, but surveys are insufficient to document population status and trends.

They are very agile on land, standing erect and walking without the waddle so characteristic of other ducks.
It usually nests in hollow trees (in South America many times in palm trees). September 6,2020. Females lay 12 eggs on average, and both sexes incubate the eggs. They will also eat small quantities of insects, spiders, mollusks, particularly during the breeding season when ducklings need more protein for proper growth and maturation.
May mate for life. Most nest failures are caused by raccoons, rat snakes and golden-fronted woodpeckers. Many breeding populations in both the United States and Mexico have historically been associated with rice culture.
Insects, snails, and other invertebrates make up less than 10% of diet.
However, similar to their goose cousins, black-bellies have adapted to feeding in agricultural environments, frequenting pastures and cattle feedlots as well as harvested rice, corn and sorghum fields when the opportunity presents itself.

Fish and Wildlife Service and occasional breeding season surveys associated with short-term research projects. September 7,2020. Black-bellied whistling ducks fly slowly in shapeless formations. Small flocks may wander well to north of normal range.Audubon’s scientists have used 140 million bird observations and sophisticated climate models to project how climate change will affect this bird’s range in the future.Zoom in to see how this species’s current range will shift, expand, and contract under increased global temperatures.Choose a temperature scenario below to see which threats will affect this species as warming increases.
Cavity nests are bare or with a few wood chips, but ground nests are woven of grasses and weeds. As with geese and swans, the plumage of both sexes of whistling ducks are very similar. They seem to readily adopt human-altered habitats, and this has helped them move north into the southern U.S. in recent decades.The Cornell Lab will send you updates about birds, birding, and opportunities to help bird conservation.
They were perplexed and bewildered at the decline of … They look most like ducks, but their lack of sexual dimorphism, relatively long-term pair bonds, and lack of complex pair-forming behavior more resembles geese and swans. September 7,2020.
The white patch in the wings appears as a stripe down its wing while at rest.In flight shows a large white patch on the upperwings. Many now use nest boxes; have also nested in chimneys, barns. The southern population breeds from Panama south into Argentina. Incubation is by both sexes, 25-30 days. The new owner and staff felt it was important to let our guests help rename the restaurant. It was great to see so many and hear them all whistling. Common south of the U.S., Black-bellied Whistling-Ducks occur in several … Races de pigeons: Dragon.
