Arctic Shorebird Demographics Network Color-marked Shorebird Resighting Report

Written by River Gates/Arctic Shorebird Demographics Network

The Arctic Shorebird Demographics Network (ASDN) is an international collaboration between shorebird biologists who are currently conducting a multi-year study to examine mechanisms behind declines of North American Arctic- breeding shorebirds. The Network collaborators’ are color-marking shorebirds at 7 sites in Alaska (Yukon Delta, Nome, Cape Krusenstern, Point Barrow, Ikpikpuk River, Prudhoe Bay and the Canning River) and 4 sites in Canada (Mackenzie Delta, East Bay and Coates Island in the northern portion of Hudson Bay, and Churchill).

We would be delighted to receive reports of color-marked shorebirds observed away from the breeding grounds. Please look for marked birds of the following species and fill out the following resighting report:

American Golden-plover Pluvialis dominica
Semipalmated Plover Charadrius semipalmatus
Bar-tailed Godwits Limosa lapponica
Whimbrel Numenius phaeopus
Ruddy Turnstone Arenaria interpres
Dunlin Calidris alpina
Western Sandpiper Calidris mauri
Semipalmated Sandpiper Calidris pusilla
Stilt Sandpiper Calidris himantopus
Pectoral Sandpiper Calidris melanotos
Long-billed Dowitcher Limnodromus scolopaceus
Red Phalarope Phalaropus fulicarius
Red-necked Phalarope Phalaropus lobatus

All ASDN birds are marked with a white (Canada) or dark green (USA) flag. The engraved flags will have a 3 letter code of letters or numbers, written in white on the green flags or written in black on the white flags, and an additional color band (e.g. red, dark blue, orange, dark green, yellow) below the flag. Most birds will also have three unique color bands on the opposite leg to further facilitate individual identification during the breeding season, as well as a US Geological Survey/Canadian Wildlife Service metal band with a unique serial number.
