DescriptionThe northern shoveler species are medium sized birds, males measuring 40 to 55 cm and weighing 500 to 1100 grams. The female birds are smaller and weigh 450 to 750 grams. The wingspan is 70 to 85 cm. The breeding shoveler drake has an iridescent dark green head. The belly and flanks are white. The breast is reddish chestnut. The speculum of shoveler drake is green. The pale blue fore wing feathers have white border, separating them from speculum. The long broad bill is gray and is tinged orange on the cutting edge and lower mandible.
HabitatThe northern shoveler species inhabit shallow lakes and water bodies with emergent and fringe vegetation. Wintering shoveler birds are seen in freshwater and brackish water bodies. They also occur in marshes, mudflats, estuaries and coastal habitats.
Feeding habitsThe broad flat bill has lamellae on the edge of the bill which acting like sieves, helping in filtering crustaceans and plankton from the water's surface. The northern shoveler species feed on invertebrates, aquatic insects, crustaceans, molluscs and aquatic vegetation.
BreedingThe northern shoveler species nest on the ground among dense grass or reeds. The breeding season is during April and May. The shoveler lay up to nine eggs.
DistributionThe breeding populations occur in North America, North Europe and North Asia. Wintering shoveler populations are found in Central and South America, Southern Europe, Africa, Indian Subcontinent, China and Southeast Asia.
Movement PatternsThe northern shoveler species is highly migratory and the birds from North America move to South America and Central America for wintering. The North European shoveler birds move southwards up to Africa for wintering. The birds from North Asia move to Indian Subcontinent, East Asia, and Southeast Asia for wintering.
Status and conservationThe global population of the northern shoveler species is estimated to be between 5,500,000 and 6,000,000 individual birds. The global population size and range is very large and hence of least conservatory concern. The shoveler species is threatened by habitat degradation, pollution and hunting.
The IUCN (International Union for Conservation of Nature) has categorized and evaluated these northern shoveler species and has listed them as of "Least Concern".
