Northern Shoveler

Anas clypeata

Perhaps the most outwardly distinctive of the dabbling ducks, the Northern Shoveler inhabits wetlands across much of North America. Its elongated, spoon-shaped bill has comblike projections along its edges, which filter out food from the water.

Interesting Information

  • The bill of the Northern Shoveler is about 6.5 cm (2.5 inches) long. The bill has has about 110 fine projections (called lamellae) along the edges, for straining food from water.

  • Northern Shoveler pairs are monogamous, and remain together longer than pairs of other dabbling duck species.

  • When flushed off the nest, a female Northern Shoveler often defecates on its eggs, apparently to deter predators.

Similar Species

  • Mallard has chestnut chest and pale flanks, as well as a smaller greenish yellow bill.

  • Blue-winged Teal and Cinnamon Teal have similar wing pattern in all plumages, but are smaller with much smaller bills.

  • Adult female and immature Northern Shoveler distantly resemble females and immatures of other duck species, but are easily distinguished by their very long bills.

Bird Sound

Male gives a nasal bray in fall courtship. Female makes various quacks. Also makes a rattling noise, unique among dabbling ducks, upon taking flight.
