Behavior

Mottled Ducks are quintessential "dabbling" ducks, meaning they feed by tipping their tails into the air to reach underwater vegetation rather than diving. Unlike many of their cousins, they are largely non-migratory, often spending their entire lives within a few miles of where they hatched. They are socially monogamous and are most frequently seen in pairs or small family groups, rarely forming the massive, noisy flocks typical of Mallards or Teals.

These ducks are notoriously wary and have earned a reputation among birders as being quite shy. In suburban environments, they may become slightly more accustomed to human presence, particularly around golf course ponds or backyard lagoons, but they still prefer to keep a safe distance. Their social structure revolves around quiet communication, utilizing soft quacks and whistles that are much less boisterous than the loud calls of the common Mallard.

Camera Tips

To capture high-quality footage of the Mottled Duck, focus on "loafing" areas. These are the flat, muddy banks or low-profile logs where ducks climb out of the water to preen and rest. Position your camera just 6 to 12 inches off the ground to achieve an intimate, eye-level perspective that makes the duck appear more prominent in the frame. If you are placing the camera near water, ensure it is angled to avoid the direct glare of the morning or afternoon sun, which can wash out the intricate brown patterns of their plumage.

Because Mottled Ducks are easily startled, a camera with a fast, silent trigger is essential. Use a "no-glow" or "black" infrared flash for nighttime or low-light shots to prevent spooking the birds. If you have a backyard pond, place your camera near natural cover like tall grasses or cattails. While you should avoid feeding them bread, which is unhealthy, a small amount of specialized waterfowl grain or cracked corn placed in very shallow water can serve as a lure to keep them within the camera's field of view for longer periods.

Set your camera to record 20-30 second video clips. This allows you to observe their unique dabbling and preening behaviors, which are much more interesting than a static image. During the spring months, pay close attention to the edges of dense vegetation where mothers might lead their ducklings. If you spot a family, avoid approaching the area directly to change SD cards; instead, wait until the birds have moved to another part of the pond to minimize stress on the brood.

Frequently Asked Questions

Mottled Ducks are most active during the 'golden hours' of early morning and late afternoon. During the heat of the day, they usually retreat to shaded banks or thick marsh grass to rest and preen.

The best way to attract them is to provide a quiet, natural water source with plenty of native aquatic plants and a 'buffer' of tall, unmowed grass at the water's edge for cover.

They are primarily herbivores, eating the seeds and roots of aquatic plants like wild rice and sedges. They also eat protein-rich aquatic invertebrates, especially during the nesting season.

Yes, they are quite common in Florida and Gulf Coast suburbs, frequently inhabiting retention ponds, golf course hazards, and canals where natural vegetation is present.

Look at the wing patch (speculum); Mottled Ducks have a blue-green patch with black borders, while Mallards have white borders. Also, Mottled Ducks have an unstreaked buffy throat, whereas female Mallards have streaking all the way up the neck.
