Limnodromus semipalmatus, the Asian (or Asiatic) Dowitcher
, breeds in southern Siberia, north Mongolia and north-eastern China in extensive freshwater wetlands in steppe and forest zones and winters on extensive coastal mudflats from eastern India to the Greater Sundas (where the largest wintering populations occur), the Philippines, New Guinea and north-west Australia (Brazil 2009, Robson, 2000).
Our finding of higher long-billed dowitcher
densities at Teshekpuk than at Prudhoe Bay is consistent with other studies, which found that dowitchers
are not a common breeder at Prudhoe Bay (Hohenberger et al., 1994) but were more common in the western strata of the coastal plain (Johnson et al., 2007).
were placed alone; recurvirostrids-American avocets (Recurvirostra americana), black-necked stilts (Himantopus mexicanus); large charadriids-black-bellied plovers, killdeer (Charadrius vociferous), and ruddy turnstones (Scolopacidae, Arenaria interpres) because they occupy a niche similar to black-bellied plovers; small charadriids-piping plovers, snowy plovers (Charadrius alexandrinus), Wilson's plovers (C.
The most abundant birds were marbled godwits (Limosa fedoa, a = 2985), small peeps (2361), willets (Catoptrophorus semipalmatus, 922), dowitchers
(891), and black-bellied plovers (Pluvialis squatarola, 252).
The armies of shorebirds--greater and lesser yellowlegs, long-billed and short-billed dowitchers
, willet, sandpipers, whimbrels, curlews, godwits, dunlins, snipes--have worked their way far to the north, foraging by day and traveling by night.
Birders can watch migratory species such as endangered clapper rails, dowitchers
, and American avocets from the platform at Elsie Roemer Bird Sanctuary.
Despite the visibility from observation sites, most calidrid sandpipers could only occasionally be identified to species, and were analyzed as "peeps." No attempt was made routinely to separate Greater Yellowlegs (Tringa melanoleuca) from Lesser Yellowlegs (Tringa flavipes), Short-billed Dowitchers
(Limnodromus griseus) from Long-billed Dowitchers
(Limnodromus scolopaceus), or Double-crested Cormorants (Phalacrocorax auritus) from Neotropic Cormorants (Phalacrocorax brasilianus).

Species already affected include American wigeons, northern shovelers, yellow rails, stilt sandpipers, Hudsonian godwits and short-billed dowitchers
. Early results of a collaborative study by U.S.
Agonistic behavior in short-billed dowitchers
feeding on a patchy resource.
Some 200 bird species, including oystercathers, plovers, sandpipers, whimbrels and dowitchers
, prefer beaches, mud flats, swamps, marshes or back bays along the North American coastline to inland areas.
Fishermen with a good sense of curiosity can encounter and enjoy many other unique shorebirds, as well, including oyster catchers, black-bellied plovers, short-billed and long-billed dowitchers
, red knots, Hudsonian godwits, whimbrels, white-rumped sandpipers, phalaropes, willets and lesser yellowlegs.
