Fall Migration Routes, Timing, and Wintering Sites of North American Ospreys as Determined by Satellite Telemetry
Satellite telemetry was used to determine fall migratory movements of Ospreys (Pandion haliaetus) breeding in the United States. Study areas were established along the lower Columbia River between Oregon and Washington; in north-central Minnesota; on Shelter Island, New York; and in southern New Jersey. Seventy-four adults (25 males, 49 females) were tracked from 1995 through 1999. Migration ro...
متن کاملSoaring and Gliding Flight of Migrating Broad-winged Hawks: Behavior in the Nearctic and Neotropics Compared
—We compared migrating behavior of Broad-winged Hawks (Buteo platypterus) at two sites along their migration corridor: Hawk Mountain Sanctuary in eastern Pennsylvania and the Kéköldi Indigenous Reserve in Limón, Costa Rica. We counted the number of times focal birds intermittently flapped their wings and recorded the general flight type (straight-line soaring and gliding on flexed wings versus ...
متن کاملWintering area DDE source to migratory white-faced ibis revealed by satellite telemetry and prey sampling.
Locations of contaminant exposure for nesting migratory species are difficult to fully understand because of possible additional sources encountered during migration or on the wintering grounds. A portion of the migratory white-faced ibis (Plegadis chihi) nesting at Carson Lake, Nevada continues to be exposed to dichloro-diphenyldichloro-ethylene (DDE) with no change, which is unusual, observed...
متن کاملPrevalence of Blood Parasites in Migrating and Wintering California Hawks
—Infectious diseases can potentially affect the seasonal migration of hawks. We tested three species of California hawks from autumn 2004 to spring 2006 for haemosporidian blood parasites (Plasmodium, Haemoproteus, and Leucocytozoon spp.). We screened 323 Red-tailed Hawks (Buteo jamaicensis), 100 Cooper’s Hawks (Accipiter cooperii), and 21 Red-shouldered Hawks (B. lineatus) for blood parasites ...
متن کاملMigration Patterns, Use of Stopover Areas, and Austral Summer Movements of Swainson's Hawks.
From 1995-1998, we tracked movements of adult Swainson's Hawks (Buteo swainsoni) using satellite telemetry to characterize migration, important stopover areas, and austral summer movements. We tagged 46 hawks from July - September on their nesting grounds in seven U.S. states and two Canadian provinces. Swainson's Hawks basically followed three routes south on a broad front, converged along the...
