(Williamsburg, VA)—Hope, a whimbrel being tracked via satellite by scientists has arrived on her breeding grounds along the MacKenzie River in Canada. She left the Eastern Shore of Virginia on 22 May and made it to breeding grounds on 14 June after traveling nearly 6,000 kilometers. This is the third year that the bird has been tracked to the same location just south of the Beaufort Sea. Her travels through three migration cycles have included more than 24,000 miles (39,000 kilometers). In addition to Hope, 3 other whimbrels were tracked this spring to breeding grounds west of Hudson Bay.
Satellite tracking represents only one aspect of a broader, integrated investigation of whimbrel migration. During the past 4 years, the Center for Conservation in partnership with The Nature Conservancy, the U.S. Fish and Wildlife Service, and Georgia Department of Natural Resources has used conventional transmitters to examine stopover duration, conducted aerial surveys to estimate seasonal numbers, collected feather samples to locate summer and winter areas through stable-isotope analysis, and has initiated a whimbrel watch program. Funding has been provided by The Nature Conservancy, the Center for Conservation Biology, The U.S. Fish and Wildlife Service, the Virginia Coastal Zone Management Program, Georgia Department of Natural Resources, The Toronto Ornithological Club, the Toronto and Region Conservation Authority, and the Northern Neck Audubon Society.

An adult female osprey on a nest in the York River. The resident pair in this territory arrived in early March and remained on the territory throughout the nesting season. Despite being resident, she never was documented to lay a clutch. The most likely explanation for large numbers of pairs not laying clutches in 2024 is that females did not reach the nutritional condition required to produce eggs. Photo by Bryan Watts.
Osprey with menhaden. Due to its high energy density, menhaden is a critical prey item for osprey populations along the Atlantic Coast and within the Chesapeake Bay. Reductions in the availability of menhaden result in a decline in the prominence of menhaden in the diet and related diet quality. Prominence of menhaden in the diet is generally believed to be linked to productivity and population stability. Photo by Bryan Watts.
