Black-bellied whistling duck

The black-bellied whistling duck, also known as the black-bellied tree duck, is a captivating bird that ranges from the southernmost parts of the United States to tropical regions in Central and South America. In the U.S., they can be seen year-round in some areas, whereas in others, they make seasonal appearances.

These ducks are quite the visual spectacle with their long red bills, gray heads, gray-brown feathers, black bellies, and striking chestnut-brown backs. Their clear whistling call is a distinctive trait, making them one of the noisier species in their habitat. There are actually two subspecies of this duck.

In terms of behavior, black-bellied whistling ducks are notably laid-back and social, often forming large groups when they are not breeding. They prefer to nest in hollow trees and have a varied diet that includes seeds, plant material, arthropods, and aquatic invertebrates. They are mostly non-migratory, though some populations in the northernmost parts of their range do relocate during the winter months.

Moreover, these ducks are renowned for their strong monogamous relationships, with both parents actively involved in raising their young.

When it comes to conservation, there is positive news: the black-bellied whistling duck is classified as "Least Concern" by conservationists. Their global population is estimated to be between 1.1 and 2 million, and it is increasing. They are common breeders in several regions and are distinguished within the duck family for their unique behaviors and characteristics.
