RUDDY DUCK
Oxyura jamaicensis
DESCRIPTION
The Ruddy Duck is a small, diving duck known for its striking appearance, particularly in males during the breeding season when they exhibit bright blue bills and chestnut-colored bodies. Females and non-breeding males are more subdued in color, featuring a grayish-brown plumage with a lighter face. These ducks are often seen in wetlands and marshes, where they engage in unique courtship displays that include elaborate head-bobbing and tail-raising behaviors.
FUN FACTS
- Ruddy Ducks are known for their unique courtship displays, which can include a series of head-bobbing and tail-raising movements that are quite entertaining to observe
- During the breeding season, males will often engage in these displays to attract females, showcasing their vibrant plumage and blue bills
- | Interestingly, Ruddy Ducks are one of the few duck species that exhibit significant sexual dimorphism, with males being much more colorful than females
- This bright coloration is not just for show; it plays a crucial role in attracting mates during the breeding season
