These birds tend to nest in holes in trees that are near wetlands, lakes, or rivers. They often find holes that Pileated Woodpeckers had previously made.
They eat aquatic invertebrates and vegetation such as fish, fish eggs, seeds, and tubers.
These ducks are compact and very fast. They can reach speeds up to 40 miles per hour.
These birds dive often to search for prey, and can stay underwater for around 1 minute. They hold their wings close to their body when they dive and often dive at the same time as others.
