Bird Island is approximately 1,300 acres (5.3 km2) adjacent to the town of Sunset Beach, North Carolina, US. Sunset Beach is on a barrier island and is the southernmost town in North Carolina.[1] Bird Island can be reached by walking along the seashore toward the South Carolina border. Due to the contour of the Atlantic Coast at this point, the direction of travel to Bird Island is approximately West-Southwest. Previously, Bird Island was separated from Sunset Beach by a tidal creek (Mad Inlet) that could be easily crossed only at low tide. Accretion of ocean sand (due to hurricane activity in the 1990s as well as environmental activity to fill in dune grass) has gradually filled in the tidal creek so that two separate islands became one.[2]
