As the first rays of dawn paint the mountains surrounding our Costa Rican retreat, a chorus unlike any other fills the air. This symphony of whistles and quacks heralds the arrival of a fascinating resident – the Fulvous Whistling-Duck.

A Global Citizen with a Local Flair

The Fulvous Whistling-Duck (Dendrocygna bicolor) is a true citizen of the world. Found in the tropical regions of the Americas, Africa, and Asia, this adaptable bird thrives in freshwater marshes, ponds, and – you guessed it – rice fields! In Costa Rica, you’ll find them gracing the wetlands and waterways across the country, with a particular fondness for the lowlands.

Striking Features for Keen Observers

Birdwatchers, rejoice! The Fulvous Whistling-Duck is a visual treat. Imagine a rich, caramel-colored body with long, elegant legs and a slender neck. Their black wings and back are adorned with a broad white band across the tail, a beacon that flashes during flight. Look closely, and you’ll notice the subtle details – a greyish-streaked neck on the adults, and fine white speckles that adorn the sides. The blue-gray bill adds a final touch to this distinctive plumage.

More Than Just a Whistle

While their name aptly describes their signature call, the Fulvous Whistling-Duck’s vocal repertoire is surprisingly diverse. Males emit a wheezy whistle, while females respond with a higher-pitched, squeaky sound. This exchange often takes place during their twilight flights between roosting and feeding grounds. Listen carefully, and you might even hear a variety of clucks, quacks, and hisses as they interact with each other.

A Glimpse into Their Unique Lifestyle

Unlike most ducks, the Fulvous Whistling-Duck is as comfortable on land as it is in water. They often graze on vegetation, but their true specialty lies in filter-feeding. Much like the Northern Shoveler, they strain fine mud through their bills, extracting seeds and tiny invertebrates – a fascinating adaptation for these resourceful feeders.

A Touch of History: From Rice Fields to Rainforest Retreats

Interestingly, the Fulvous Whistling-Duck’s presence in Costa Rica is a relatively recent development. Their arrival coincided with the introduction of rice cultivation in the late 19th and early 20th centuries, providing them with ideal food and habitat. Today, they are a common sight in many areas, including the wetlands and waterways surrounding our mountain retreat.
