Why Count & Study Hawks?

Scientists at Hawk Mountain study the patterns and processes of raptor migration. They use the Sanctuary’s long-term migration database to monitor changes in raptor populations.  Monitoring raptor populations is important because raptors are sensitive bioindicators at the tops of food chains, and changes in the numbers of raptors reflect changes in the health of the environment.  Rachel Carson used declining counts of immature bald eagles at Hawk Mountain in her book Silent Spring as evidence of DDT’s harmful effects on the environment.
