Wintering Ecology of Adult North American Ospreys
North American ospreys typically migrate long distances to their wintering grounds in the tropics, yet very little is known about the wintering ecology of these birds. USGS and other researchers used satellite telemetry from 1997–2013 to determine the time ospreys spent on wintering grounds. Scientists also examined wintering area characteristics and space use of ospreys from the East Coast, Midwest, and Pacific Northwest.
