In winter, AuSable Point Campground is closed to camping, but open to walking and birding. It can be a great place to find mixed flocks of wintering ducks. These include common species such as greater and lesser scaup, common goldeneye, and common merganser, but look for less common species mixed into the flocks.
Watch too for bald eagles which are regularly found here.
When not frozen, the marsh itself (which borders the campground road) can also be good for migrating waterfowl, and keep an eye open for rusty blackbirds in migration with larger flocks of red-winged blackbirds. The marsh also provides breeding habitat for birds such as wood duck, blue-winged teal, Wilson’s snipe, Virginia rail, and American bittern, among others.
