As one of the last remnants of the original Outer Banks landscapes, the Donal C. O'Brien, Jr. Audubon Sanctuary is a vital resource for birds and wildlife along the Currituck Sound and across the entire Atlantic Flyway. With its extensive marshes, waterways and diversity of upland and maritime forest, the 2,600 acres of preserved land contribute to major environmental and wildlife conservation efforts for the health of our birds, wildlife and local community.
