Ecological Niche- Wood Duck

The wood duck is found in north america and I believe it is best looking duck in North America. Wood ducks nest in wetlands such as rivers, swamps, lakes, and flooded timbers. Wood ducks diet consist of insects, small fish, nuts, berries and seeds

Favorite Biome

My favorite biome is the wetlands, which consist of marshes, bogs, and swamps. I think wetlands are very interesting and unique because of the different animals that live there such as reptiles, birds, insects and mammals. oil-spill-marshland-louisiana-061710.jpg
