Trumpeter Swans are considered the largest waterfowl species native to North America, and they are known for their graceful movements and their beautiful white plumage. These swans are often found near water bodies such as lakes, rivers, and wetlands. Here are some fascinating facts about the biology, diet and more of Trumpeter Swans.

Biology

Trumpeter Swans can grow up to six feet long, and they have wingspans that can reach up to ten feet. They weigh anywhere between 16 – 30 pounds. They are typically white in color, with black bills, legs, and feet. They have long necks which they use to scope out their surroundings. Additionally, these swans have sharp eyesight, which allows them to spot predators from a distance.

The lifespan of a Trumpeter Swan in the wild is approximately 20 years. However, swans in captivity can live up to 30 years or more.

Diet

Trumpeter Swans are herbivores and they mostly feed on underwater plant material such as sedges, pondweed and wild rice. They also feed on insects, mollusks, and fish. They have a unique feeding method, where they dip their necks deep into the water and pluck the plants and insects using their beak.

Breeding

Trumpeter Swans typically breed in the spring, after which they lay their eggs in nests built on the ground near water bodies. The female swan lays 4 – 6 eggs per clutch, and both parents take turns incubating the eggs until they hatch, which takes around 32 – 37 days. Once the cygnets are born, both parents take turns feeding and protecting them. They can swim within the first 24 hours after hatching and are completely independent within three or four months.

Conservation

Trumpeter Swans were once on the brink of extinction due to overhunting and loss of habitat during the late 1800s. As a result of conservation efforts, they were reintroduced into their former range, and the population has since grown. These swans are now protected under the Migratory Bird Treaty Act.

In conclusion, Trumpeter Swans have a unique biology, diet, and breeding pattern that sets them apart from other birds. These graceful and peaceful creatures are a symbol of conservation success, and they continue to thrive in their native habitats.
