Longevity records of North American birds. In general, they have plump bodies, short tails, longish necks with small heads, and long, pointed wings for fast, long distance flight. Most distinctive field mark is black underwing, only seen in flight. An extremely long-distance migrant, the Hudsonian Godwit makes a nonstop flight of several thousand miles each fall. Hudsonian Godwits breed in the arctic, especially where the boreal forest (taiga) gives way to wet tundra meadows and bogs. The English term "godwit" was first recorded in about 1416–7 and is believed to imitate the bird's call. In recent decades, observers have documented flocks in Amazonian Brazil landing on muddy islands that emerge as river levels fall during the dry season. This how Wikipedia describes the Hudsonian Godwit…. Because of their remote arctic breeding habitat, Hudsonian Godwit population trends are not well known. Sandpipers also demonstrate a wide variety of bill sizes and shapes that reflect different feeding behaviors; there are species with short, stubby bills, thin medium length bills, long, thin bills, and decurved bills. This transitional zone is a mosaic of marshes and drier hummocks that support small trees and shrubs. The upper parts are mottled brown and the underparts are chestnut. Alfred A. Knopf, New York, NY, USA. Long bill, slightly upcurved and pink with black tip. Very well concealed, extremely hard to find. Although not considered endangered, populations of the Red Knot in eastern North America have been steeply falling because of over harvesting of the Horseshoe Crab; the eggs of which serve as their main food source during a critical migration stop-over in the Delaware Bay. Nests are scrapes or depressions in the ground, barely lined with twigs, dead leaves, sedges, bog rosemary, spruce needles, grasses, mosses, and lichens. Territories vary in size, and pairs may nest far from the initial displaying area, suggesting that females perhaps select the nesting site. var sc_security="340ce72a"; Migrants and wintering birds tend to be sociable, occasionally jousting with flockmates but not maintaining winter feeding territories as some shorebird species do. Hudsonian Godwits are thought to breed at two years of age. Long bill, slightly upcurved and pink with black tip. (2011). Hudsonian Godwits breed in Alaska and Canada and spend the non-breeding season in Chile and Argentina. White rump, white wing-bar, black underwings visible in flight. The birds are hunted to such an extent that they are exceedingly wary. Nests average about 5.6 inches across and 1.7 inches tall. This kind of boggy habitat is called “muskeg” (a Cree word) and features acidic soils rich in sphagnum mosses and sedges. Territorial males spiral erratically upward on rapidly beating wings, calling until they reach a point high above the territory. There are three well-separated breeding populations; in south-central and western Alaska, along the northwest coast of Canada (Mackenzie and Anderson river deltas) and within the Hudson and James Bay region of northern Canada. Hudsonian Godwit: Large sandpiper with white-scaled, brown-black upperparts, black-barred chestnut-brown underparts. During the breeding season, monogamous pairs form on the breeding grounds, through a courtship process of display flights. Efficiency of flight is better with longer, narrower wings, particularly with longer hands. Swift, powerful undulating flight. Legs and feet are blue-gray. In winter plumage it is greyish-brown above and white below and looks very similar to the common bar-tailed godwit and almost identical to the slightly more numerous black-tailed godwit. Some great shots there, David. Both parents defend the nest site and tend chicks until they fledge (uncommon in shorebirds). The nest is usually in a sedge marsh, set on a dry hummock, with dwarf birch or other shrubs close by. A. and A. S. Love. The Hudsonian godwit is a large greyish-brown wader with a long, slightly upcurved , bi-coloured bill; long black legs and long wings. Lutmerding, J.
