英文小作文：

My Favorite Animal - Eider Ducks

Eider ducks are my favorite animals because of their unique beauty and interesting behavior. They live in cold northern waters and are known for their brightly colored feathers and their unique way of nesting. The males build huge mounds of mud and grass to protect their eggs, and the females incubate them for several weeks before they hatch. Eider ducks are also known for their long lives, which can exceed 20 years in the wild. I enjoy watching them swim and nest, and I hope to see them in their natural habitat one day.
