Description
Size: 51 cm.

Habits: Northern Shovelers prefer shallow saltwater or freshwater wetlands like marshes, swamps, lakes, and lagoons. As they are not not aggressive birds, they can get along with other dabbling ducks, diving ducks, whistling ducks and Shelducks.

The male Shoveler has greenish feathers on the head and neck, the breast and belly are white, the back is black and white, and the wings have a chestnut hue, with the inner wings being bluish. The female's belly and breast are white, the body is a brownish color, and the inner wings are bluish. The bill of the Northern Shoveler has hair like lamellae that filter the water and capture the small plankton. The most distinctive feature is their large spatulate bill. It is twice as wide at the tip than it is at the base. This uniquely shaped bill gives rise to Northern Shovelers also being called "spoonbills".

Nesting: Season- in the Palaearctic Region (N. Europe etc.) April to June. Nest- a pad of grass and rushes, on marshes etc. Eggs- 7 to 16, pale stone or buff, sometimes with a greenish tinge. Incubation by the female alone begins immediately after all the eggs are laid and can last 23 to 25 days. The ducklings are born precocial and start following the female almost immediately.

Average lifespan-223 months

Economic Importance and Threats
Threats:  Anthropogenic
(The species is threatened by habitat loss and is occasionally killed by collisions with power transmission lines. The species may suffer from reproductive impairment as a result of selenium (Se) accumulation in liver tissues (selenium contained in sub-surface agricultural drain-water used for wetland management in California led to bioaccumulation of the element in the food chain).)
Threats:  Natural threats
(It is susceptible to avian influenza and avian botulism so may be threatened by future outbreaks of these diseases.)
Importance:  Commercial
(Northern Shovelers are a game bird. Hunters often shoot them due to their resemblance to mallards. They are often referred to as "neighbor's mallards," because some hunters give them to their neighbors and keep the more tasty mallards for themselves.)

Ecology
Habitat:  Estuarine
Trophic Level:  Consumer
Prey:  Water insects, snails and plankton, fish, spawn and small quantities of vegetable shoots.
IUCN Status:  Least Concern
