Depending on the time of year, common visitors to the area include the American avocet, barn swallow, eastern kingbird, loggerhead shrike, reddish egret, and willet.

American Avocet

One of the most interesting birds found at the sanctuary is the American avocet. American avocets display grey plumage around the head in winter or rusty plumage during breeding season. They have grayish legs and long upturned bills, which allow them to easily sift through the water, looking for prey. These exotic birds seem like they don’t belong on the Gulf Coast, but flocks of them wade in the tidal flats near the shore.

Another species of bird found at the sanctuary is the barn swallow. The barn swallow is the most widespread swallow in the world and is found throughout the United States. They are easily identifiable by their dark blue back and cinnamon colored throat. These birds often perch on the barbed wire along Rettilon Road or near the sand dunes on the beach.
