Northern Shoveler, Cuchara común

Anas clypeata

Description:

Breeds in northern areas of Europe and Asia and across most of North America, wintering in southern Europe, Africa, the Indian subcontinent, Southeast Asia, and Central and northern South America. This duck is unmistakable due to its large spatulate bill. The breeding drake 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. 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 cutting edge and lower mandible. The female's forewing is gray. They feed by dabbling for plant food and aquatic invertebrates, often by swinging its 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 – 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.
