Fat reserves and migration of Red-necked Phalaropes ( Phalaropus lobatus ) in the Quoddy region, New Brunswick, Canada
Arrival, length of stay, fat deposition, flight range, and migration strategy of Red-necked Phalaropes (Phalaropus lobatus) were studied during the 1981–1982 autumn migrations through the Quoddy region, New Brunswick, Canada. Arrivals at this staging ground reflected the sequence in departures from...
