Sea birds are a diverse group of birds that are specially adapted to life in marine environments. They are often found along coastlines, on open oceans, and near islands. Common examples include seagulls, albatrosses, and puffins. These birds typically have strong wings for long-distance flying and webbed feet for swimming or diving. Many sea birds feed on fish and other marine organisms, using various hunting techniques. Some, like the tern, catch fish by diving into the water, while others, like the pelican, scoop fish up with their large bills. Sea birds also play important roles in marine ecosystems, helping to control fish populations and contributing to nutrient cycling.
