When submitting eBird observations at  Ausable Marsh Wildlife Management Area, it is most helpful to start a new checklist for each hotspot in the wildlife area. Use the general hotspot when you have a checklist that includes multiple locations or if no other hotspot or personal location is appropriate for your sightings.

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.

Ausable Marsh has wildlife habitats ranging from marsh and sandy dunes to floodplain forests. Watch 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 habitats for birds such as Wood Duck, Blue-winged Teal, Wilson’s Snipe, Virginia Rail, and American Bittern, among others.

The primary purposes of Ausable Marsh Wildlife Management Area (WMA) are wildlife management, wildlife habitat management, and wildlife-dependent recreation.

Over thousands of years, water-borne materials have been deposited by the Ausable River at its juncture with Lake Champlain. This has created a fertile delta at the river's mouth which has been utilized by mankind for centuries. Before state ownership, the area was used primarily for agriculture and timber harvesting. Today, Ausable Marsh is managed by the DEC for a variety of recreational and scientific purposes, including natural resources education, wildlife observation, photography, fishing, trapping, hunting, and canoeing. One of the primary objectives is to provide nesting and feeding habitat to a variety of waterfowl.

Ausable Marsh has wildlife habitats ranging from marsh and sandy dunes to floodplain forests. These habitats support many types of fish and wildlife.
