With its open coastal water and abundant prey, the refuge plays a significant role as migration and wintering habitat for the federally protected bald eagle. The bay area also provides prime migration habitat for the peregrine falcon. Many state-protected species use the refuge, including the common loon, pied-billed grebe, osprey, common tern, northern harrier and upland sandpiper.
