Northern Pintail

Description:

The Northern Pintail is a widely occurring duck which breeds in the northern areas of Europe, Asia and North America. It is strongly migratory and winters south of its breeding range to the equator. This is a fairly large duck, with a long pointed tail that gives rise to the species' English and scientific names. Fast and graceful fliers, pintails are equipped with long wings, small heads, and long necks that seem built for streamlined aerodynamics. Both sexes have blue gray bills and gray legs and feet. The drake is more striking, having a thin white stripe running from the back of its chocolate-colored head down its neck to its mostly white undercarriage. The drake also has attractive gray, brown, and black patterning on its back and sides. The hen's plumage is more subtle and subdued, with drab brown feathers similar to those of other female dabblers. Hens make a coarse quack and the drakes a flute-like whistle. It feeds by dabbling for plant food and adds small invertebrates to its diet during the nesting season. It is highly gregarious when not breeding, forming large mixed flocks with other species of duck. The Pintail walks well on land, and swims buoyantly. It has a very fast flight, with its wings slightly swept-back, rather than straight out from the body like other ducks. In flight, the male shows a black speculum bordered white at the rear and pale rufous at the front, whereas the female's speculum is dark brown bordered with white, narrowly at the front edge but very prominently at the rear. The winter diet is mainly plant material including seeds and rhizomes of aquatic plants, but the Pintail sometimes feeds on roots, grain and other seeds in fields, though less frequently than other Anas ducks. During the nesting season, this bird eats mainly invertebrate animals, including aquatic insects, molluscs and crustaceans.

Habitat:

The Northern Pintail has been called the "nomads of the skies." due to their wide-ranging migrations. This dabbling duck breeds across northern areas of Eurasia south to about Poland and Mongolia, and in Canada, Alaska and the Midwestern United States. It winters mainly south of its breeding range, reaching almost to the equator in Panama, northern sub-Saharan Africa and tropical South Asia. Seen at a marshy wetland.
