Quick Answer
Diver ducks tend to roost in areas with low-lying vegetation, such as marshes, swamps, and shallow lakes. They often prefer spots with dense cover, often near the water's edge. Roosting sites with minimal human disturbance are also a priority.
Habitat Preferences
Diver ducks are often found roosting in areas with low-lying vegetation, particularly those with dense cover such as cattails, sedges, and algae. These areas provide ideal shelter from strong winds, harsh weather, and potential predators. For example, the Common Merganser typically roosts in areas with dense vegetation, often near the shoreline. When selecting a roosting site, diver ducks tend to avoid areas with excessive human activity, such as commercial fishing or recreational boat traffic.
Roosting Height and Distance
When selecting a roosting location, diver ducks typically choose spots at a medium to high elevation, often 2-5 feet above the surrounding water level. This allows them to maintain a safe distance from potential predators while still being able to quickly escape if necessary. It is not uncommon for diver ducks to roost in areas with shallow water, often as shallow as 1-2 feet, as long as there is adequate cover and shelter.
