An investigation into raptor migration along the southern coast of Alaska was initiated in 1982. Spring and fall counts of migrant raptors were recorded in the Malaspina Glacier area west of Yakutat Bay. Biologists determined that there was a sizable flight of raptors following the coast of Alaska in both the spring and fall. However, the land forms at Malaspina Glacier did not concentrate the flight sufficiently for the biologists to accurately assess the magnitude of the flight. In conclusion, two areas have been located which hold promise for us. The geographic structures at both locations would concentrate birds both in the spring and fall. This is obviously a bonus, as any equipment that was flown in at considerable expense could possibly be left at the same location and used twice yearly. The Yakataga area is more accessible and would provide the potential for better accommodations. The Grand Plateau Glacier area holds the best hope for great concentration.
