Northern Shoveler migration

Northern Shoveler migration

Socially, they occasionally work together in groups while feeding, rotating like a pin-wheel, stirring up the surface water and skimming it for food particles.

The Northern Shoveler was first described in 1758 by Carolus Linnaeus, Swedish botanist, physician and zoologist.

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 Northern Shoveler comprises less than 2% of the total duck population in Minnesota. If the female is interested, she flies away with the chosen male.

Its overall declining population trend, however, is similar to that for many ducks in the state (Cordts 2015).

The female Northern Shoveler also has a brownish speckled body. The female tends to them and protects them until they learn to fly at about 8 weeks. The Northern Shoveler starts displaying in winter, and continues during the return migration. Numbers decline in Nov, but later reports are common, such as the 204 on 14 Dec 2002 in Scotts Bluff Co, and 56 at Harlan Co Reservoir, Harlan Co 18 Dec 1998. Each male tries to lead her away by swimming away or by short flight. The young leave the nest soon after hatching, and find their own food. Identification: Northern Shoveler is so named for its distinct large spoon-shaped bill. Adult female Northern Shoveler, breeding plumage; Oregon, May Malheur NWR, Oregon, May 2004.; photographer Gerrit Vyn The Northern Shoveler is a common holarctic duck with a high degree of morphological and feeding specializations.

Wintering habitat includes fresh and brackish coastal marshes, and ponds. Typically, several males court one female by swimming around her on water. Primary migration commences in Sep and the species becomes more common and widespread; peak numbers are attained in mid- to late Oct. The bill os olive green with fleshy orange in the gape area and speckled with black dots. The female's belly and breast are white, the body is a brownish color, and the inner wings are bluish. Copulation takes place in the water. The female usually lays 8 to 12 eggs, and she alone incubates them. Saltwater wetlands are generally avoided. Migration. The nest of a Northern Shoveler is a shallow depression on the ground, lined with grasses and weeds with an inner layer of down.
