The Honey Island Swamp is rich in wildlife and is the home of many different species, including but not limited to: alligators, wild boars, black bears, racoons, nutrias, owls, eagles, snakes, turtles, and, of course, fish. Alligators can often be seen lounging on the banks and bathing in the sun. The most common sightings include red wolves, white tail deer, and wild boar, but only a select few have been able to spot the elusive Florida cougar. Birds are often seen tangled in the trees as visitors drift by underneath, including Yellow-crowned Night Herons, White Ibises, and Anhinga.
Considered a trademark of Louisiana culture, Crawfish often attract their fair share of attention to this marshland, but the wide variety of fish keep people coming back. Fishermen can often find an abundance of flathead catfish, bluegill, sunfish, largemouth bass, and buffalo fish under the water of Honey Island Swamp.
