Hooded Merganser

Lophodytes cucullatus

With an oversized, collapsible crest and a piercing yellow eye, the Hooded Merganser is a master of the wooded swamp. This small but striking 'sawbill' is a favorite for backyard observers with access to quiet water.

Behavior

The Hooded Merganser is a shy and secretive diving duck, often found in smaller, quieter bodies of water than its larger merganser cousins. They are incredibly agile underwater, using their specialized serrated bills to grasp slippery prey. Unlike many waterfowl that tilt their bodies to feed, 'Hoodies' disappear completely beneath the surface, often staying submerged for several seconds while they hunt among submerged logs and vegetation.

Socially, they are usually found in pairs or small groups rather than large rafts. During the breeding season, males perform elaborate displays, expanding their oversized crests to their fullest extent while throwing their heads back and emitting a low, frog-like croak. They are one of the few duck species that nest in tree cavities, often utilizing old woodpecker holes or man-made nesting boxes located near the water's edge.

Camera Tips

To capture high-quality footage of Hooded Mergansers, placement is everything. These ducks are notoriously skittish around human movement, making a well-hidden trail camera the perfect tool for observation. Look for 'loafing logs'—fallen timber that extends into the water. Mergansers use these spots to climb out of the water, dry their feathers, and preen. Position your camera on a nearby tree or stake, aiming it about 12-18 inches above the surface of the log for the best eye-level perspective.

Because Hooded Mergansers are diving ducks, they spend a significant amount of time underwater. To avoid capturing 'empty water' videos, set your camera to a longer video trigger (at least 20-30 seconds) or use a fast-recovery photo mode. If your camera allows, a high shutter speed is essential; their movements while preening or taking off from the water are incredibly fast, and a slow shutter will result in motion blur. Avoid using heavy scents or lures, as these birds rely entirely on sight and natural movement to find food.

One of the best ways to guarantee activity is to install a wood duck nesting box on your property and mount a camera nearby. Hooded Mergansers are secondary cavity nesters and will frequently investigate these boxes starting in late winter. Aim the camera at the entrance hole from a side angle to capture the dramatic moment the female enters or the ducklings make their first leap. Early morning light is your best friend here, as it highlights the iridescent feathers of the male's head without creating the harsh glare often found on open water during midday.

Similar Species

Wood Duck

Wood Ducks have a wider, flatter bill and lack the large white fan-shaped patch on the crest.

Buffleheads are smaller with a rounder head and a white patch that wraps further around the back of the skull.

Common Merganser

Much larger with a longer, thinner red bill and lacks the oversized fan-shaped crest.

Frequently Asked Questions

Hooded Mergansers are diurnal, meaning they are active during the day. You are most likely to see them foraging and displaying in the early morning and late afternoon when light is softer and human activity is low.

If you have a pond or stream, you can attract them by providing nesting boxes specifically designed for Wood Ducks, which Hooded Mergansers will readily use. Maintaining healthy, clear water with plenty of natural submerged debris helps support the fish and crayfish they eat.

They are primarily carnivores. Their diet consists of small fish, aquatic insects, and crustaceans like crayfish. Their specialized serrated bills allow them to grip slippery prey that other ducks can't catch.

They can be common in suburbs if there are quiet, wooded ponds or retention basins nearby. They generally avoid large, busy lakes used for motorized boating, preferring secluded spots with lots of overhanging trees.

While both have crests, the Hooded Merganser has a much thinner, black 'sawbill' compared to the Wood Duck's wider, colorful bill. The male merganser also has a large white patch on its crest, whereas the Wood Duck is known for its intricate green and white facial patterns.
