Foraging geese

Detailed Description

Canada Geese (Branta canadensis) grazing on eelgrass (Zostera marina) in Puget Sound, Washington. David Ward, biologist at the USGS Alaska Science Center, reported at the "Future of Pacific Northwest Seagrasses in a Changing Climate" workshop that temperature-induced shifts in the growing season of eelgrass can affect migratory pathways of waterfowl, such as Black Brants (Branta bernicla nigricans), that depend on this seagrass.
