Annual summary reports of Red Knot breeding ecology studies on the Seward Peninsula since 2011.

We have gathered information on all known recaptures and resightings of marked Dunlin throughout the East-Asian Australasian flyway, as well as opportunistically at other locations. The objectives of this study were to (1) identify regional connectivity patterns within and among subspecies of Dunlin migrating and wintering along the EAAF, (2) examine the regional connectivity patterns of Dunlin of unknown subspecies captured and marked at sites on the nonbreeding grounds, (3) examine recovery patterns of arcticola Dunlin initially captured on the NW and NE portions of their Alaska breeding range, (4) examine recovery patterns of arcticola males and females, (5) examine recovery patterns of arcticola Dunlin of different...

The roselaari subspecies of Red Knot is one of the rarest shorebird populations breeding in North America, based on a the current population size estimate of 17,000 individuals (Carmona et al 2013). As a result of suspected declines,the roselaari subspecies has been designated as threatened by the Committee on the Status of Endangered Wildlife in Canada and was petitioned for listing under the U.S. Endangered Species Act. The U.S. Fish and Wildlife Service’s decision to not conduct a full status review for listing was based on the lack of substantial information identifying threats and population trends (USFWS 2011). The apparent low population size coupled with the scarcity of information on many demographic and...

The Pacific Flyway Winter Brant Survey (WBS) has been conducted annually since 1981 as part of a cooperative effort by the U.S. Fish and Wildlife Service, Canadian Wildlife Service, Mexico, and the Pacific U.S. states, to estimate the abundance of the Pacific black brant (Branta bernicla nigricans) in their principal wintering areas along the Pacific Coast (in Baja, Mexico, California, Oregon, Washington, British Columbia, and Alaska). The survey is conducted each winter in January-February by a composite of ground and aerial crews, with the Alaska portion being conducted by the Alaska Region of USFWS Migratory Bird Management. The primary objective of the Alaska survey component is to provide an annual index of...

This file contains information on Dunlin resightings and recaptures along the East Asian-Australasian flyway, and elsewhere, including date and time, location, and band combination of resighting or recapture, as well as tagging information. A portion of these data (as indicated by field ‘Lagasse.2020’) were used to determine migration along the East Asian–Australasian Flyway (EAAF). General methods are available in Lagassé et al. 2020. Dunlin subspecies exhibit regional segregation and high site fidelity along the East Asian–Australasian Flyway. The Condor: Ornithological Applications 122. https://doi.org/10.1093/condor/duaa054. For this analysis data were restricted to resightings within the EAAF that occurred...
