Aptly nicknamed the spoonbill, the northern shoveler has the largest bill of any duck in North America. The bill is longer than the duck's head, and has a flattened wide tip perfect for "shoveling" along the water's surface for food. But what else makes shoveler ducks so distinctive?
Common Name: Northern Shoveler, Shoveler, Spoonbill Duck
Scientific Name: Spatula clypeata (formerly Anas clypeata)
Scientific Family: Anatidae
Appearance and Identification
While the northern shoveler's bill is its most unique feature, there are other field marks that stand out on both males and females. Birders who are familiar with all these features will have no trouble identifying the spoonbill, even if they don't see the characteristic bill.
- Bill: Broad, spatulate, longer than the head, black on males and smudged orange-gray on females
- Size: 18-20 inches long with 29-31-inch wingspan, large bill, short tail
- Colors: Black, iridescent green, buff, white, chestnut, brown, orange, powder blue, gray
- Markings: Males have an iridescent green head that can look black when in shadow or poor light. The breast is white while the abdomen and flanks are chestnut with a white patch at the rear. The dark back shows some brown mottling and white streaking. The black rump may also show iridescent green. Females are mottled brown, buff, and black overall with darker upperparts, finer streaking on the head, and a faint dark eye line. Both genders have yellow eyes, bright orange legs and feet, an iridescent green speculum, and a powder blue wing patch visible in flight.
Juveniles look similar to adult females but have a grayish wash on the head, neck, and upperparts until they molt into their adult plumage.
Foods, Diet, and Foraging
Like all dabbling ducks, northern shovelers are omnivorous and will sample a wide variety of available foods. Aquatic plants, grains, aquatic insects, and mollusks all make up part of their diet. Though shovelers are classified as dabblers, they rarely tip tip up to feed and instead skim their broad bills along the surface of the water, appearing to nibble or swing their bills back and forth as they swim.
This efficiently strains insects and plants through the lamellae that line the edges of the broad bill so the bird doesn't miss a morsel.
Habitat and Migration
Shoveler ducks prefer freshwater lakes, marshes, estuaries, and wetlands with shallow muddy edges. Their summer range extends from Alaska through central Canada south to the mountain regions of Colorado and northern New Mexico and as far east as the St. Lawrence River and Massachusetts Bay. In winter, northern shovelers migrate to the Pacific coast and the southern United States, as well as into the Caribbean, Mexico, and northern South America. These birds can be found year-round in parts of the mountain west, including Utah, southern Idaho, and eastern Oregon and Washington.
Northern shovelers are found in similar habitats in Europe and Asia, staying year-round in parts of the United Kingdom, France, and around the Mediterranean Sea. In winter, these ducks spread out to southern Europe, northern Africa, and the Nile River region and stretching through the Middle East, India, and Southeast Asia into eastern China and Japan. During the breeding season, these ducks are more common in Scandinavia, eastern Europe, Russia, and China.
Rare vagrants have been reported in Australia.
Within their range, these ducks may also occasionally be found in suburban habitats where ponds or lakes are found in parks, especially if the area is rich in other suitable habitats.
These ducks are not very vocal, though males do use different calls as part of their courtship behavior. Typical calls include a slow, nasal bray with only a few clunky syllables, as well as a noisy rattle upon takeoff.
Northern shovelers are typically found in pairs or alone during the breeding season, but can gather in much larger flocks mixed with other types of ducks, particularly teal or other dabblers, during the winter. When taking flight, these ducks leap quickly into the air for an abrupt takeoff.
The female builds a shallow scrape nest that may be close to water or could be farther from water in a grassy area, and the depression is lined with down, dry grass, and weeds.
The elliptically-shaped eggs are olive, buff, or greenish, and there are 5-20 eggs in a typical brood. The female parent incubates the eggs for 22-26 days, and the precocial chicks can leave the nest within hours of hatching. The female parent will care for the young ducklings and lead them to food for an additional 40-65 days until their first flight. Mated pairs of northern shovelers only raise one brood per year.
Attracting Northern Shovelers
Like all ducks, the northern shoveler is not a typical backyard bird. Birders interested in seeing this brightly patterned duck, however, can visit a variety of shallow marshlands where insecticide use is minimal and wetland edges are allowed to erode to produce mud and weeds for these ducks to forage.
While these ducks are widespread and not considered endangered, they are at risk from toxic contamination, fishing line tangles, and similar threats. Habitat preservation will help conserve their numbers, and in many areas, northern shovelers are carefully managed as a game species for regulated hunting.
