Color-marked Shorebird Resighting Report

The Arctic Shorebird Demographic 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 and a color band. 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.

Example of how to report color banded and flagged shorebirds. Colors are read from top to bottom, bird’s left to the bird’s right.

Upper Left (UL) = green flag, alpha code= CLM, red

Lower Left (LL) = metal band

Upper Right (UR) = no bands

Lower Right (LR) = yellow, orange, red

Observer confidence (circle one, see details below) 5 4 3 2 1
Observer Confidence Scale:

5: High confidence: Able to clearly read flag code and distinguish color band combination, confident of species identification. Verified by picture.

4: Moderately-high confidence: Able to read flag code and/or colors combo after a few attempts, mostly confident of the flag code and/or color combo, confident of species identification. Picture taken but does not verify the individual identification.

3: Moderate confidence: Able to read most of flag code and colors combination, not 100% sure of location of bands, alpha-code or color combos.

2: Moderately low confidence: Able to see that the bird was marked and see some of the flag code or color combo. Not able to confirm flag code or color combo. Confident in species identification.

1: Low confidence: Able to see that the bird was marked but could only read some of the alpha coded flag and/or color combo. Not certain of the species identification.
