27-11-2024 MARJAL DE MOROS PUCOL, VALENCIA - NORTHERN SHOVELER (MALE) (Spatula clypeata)

The Northern shoveler (Spatula clypeata) is a widespread species of duck unmistakable in the northern hemisphere due to its large spatulate bill. In Britain, it is known simply as the shoveler. One part of its scientific name Spatula is the Latin for a "spoon" or "spatula"; the other part is derived from the Latin clypeata and can be translated as "shield-bearing".

During the breeding season, the male of this species has an iridescent dark green head, white breast, and chestnut belly and flanks. In flight, pale blue forewing feathers are revealed, separated from the green speculum by a white border. In early fall the male will have a white crescent on each side of the face. In non-breeding (eclipse) plumage, the male resembles the female. The female is a drab mottled brown like other dabblers, with plumage much like a female mallard, but easily distinguished by the long broad bill, which is gray-tinged with orange on the cutting edge and lower mandible. The female's forewing is gray.

Northern shovelers breed in wide areas across Eurasia, western North America, and the Great Lakes region of the United States. They are strongly migratory and winter in southern Europe, Africa, the Indian Subcontinent, the Caribbean, northern South America, the Malay Archipelago, Japan, and other areas. In North America, they winter south of a line from Washington to Idaho, from New Mexico east to Kentucky, and along the Eastern Seaboard as far north as Massachusetts. Northern shovelers are birds of open wetlands, such as wet grassland or marshes with some emergent vegetation. Preferred feeding areas include lakes, estuaries, coastal shorelines, salt marshes, flooded fields, and agricultural ponds.

Northern shovelers are social ducks that live in small flocks and coexist peacefully with many other species. They feed during the day by dabbling for plant food, often by swinging their bill from side to side and using the bill to strain food from the water. Their wide-flat bill is equipped with well-developed lamellae; these are small, comb-like structures on the edge of the bill that act like sieves, allowing the birds to skim crustaceans and plankton from the water's surface. This adaptation gives them an advantage over other puddle ducks, with which they do not have to compete for food resources during most of the year. Thus, mud-bottomed marshes rich in invertebrate life are their habitat of choice. During the midday heat, the birds usually rest on land near the water. Northern shovelers are fairly quiet and communicate with each other only in certain situations; males have a low clunking call, whereas females have a light Mallard-like quack.
