The North American race includes two disjunct breeding populations both of which winter primarily in Central and South America. The western population breeds in Alaska and the Northwest Territories of Canada. The eastern population breeds south and west of Hudson Bay in Manitoba and Ontario. It has generally been believed that the western population follows a Pacific Coast migration route between breeding and wintering areas and that the Hudson Bay population follows an Atlantic Coast route. Both populations are of high conservation concern due to dramatic declines in recent decades. For more than a decade, scientists have believed that the seaside of the lower Delmarva Peninsula in Virginia played a significant role in the life cycle of the whimbrel. During spring migration in the mid-1990s, Bryan Watts from the Center for Conservation Biology at the College of William and Mary and Barry Truitt of The Nature Conservancy documented the densest concentration of whimbrels ever recorded in the western hemisphere within the barrier island lagoon system of the lower Delmarva Peninsula. Since that time, it has been believed that the Eastern Shore of Virginia represents a critical, coastal staging area where birds feed on the staggering numbers of fiddler crabs that inhabit the lagoon system and build up energy reserves before making their last overland flight to the breeding grounds. However, it has always been assumed that the birds staging along the lower Delmarva were exclusively from the Hudson Bay population. The flight documented in spring 2008 (see Winnie's map) has forced a change in thinking regarding the origin of birds using this stopover site. Beginning in 2008, the Center for Conservation Biology collaborated with The Nature Conservancy to investigate the stopover ecology of whimbrels along the Delmarva Peninsula. The study includes aerial surveys to estimate seasonal numbers, traditional transmitters to examine stopover periods, and satellite transmitters to document migration pathways and breeding destinations for birds leaving the site. The seaside of the Delmarva Peninsula has been recognized as a globally important bird area, a hemispheric shorebird reserve, and a UNESCO biosphere reserve. The discovery that whimbrels use the site as a terminal staging area before embarking on a transcontinental flight suggests that the site is uniquely suited to provide the tremendous amount of energy required to prepare birds for such a flight. Continued research planned by CCB and TNC in Virginia will investigate whimbrel stopover ecology and the broader strategic importance of this site to whimbrel populations. In 2010, Georgia Department of Natural Resources began tracking Whimbrel from another important migration stopover on the east coast of North America. Georgia's barrier island and salt-marsh complex provide excellent stopover habitat for refueling on their migration from their wintering grounds in South America to the breeding grounds in the Arctic. Names for the Vriginia Whimbrels are landmarks near where the Whimbrel congregate on the Eastern Shore of Virginia (Hope Creek, Box Tree, Fowling Point, Elkins Marsh, Hope Creek, Indian Creek, town of Machipongo, Webb Island, Ramshorn Channel, Mill Creek, and Kitt Creek).
