American Alligator at Audubon Zoo

Meet American Alligators at Audubon Zoo

American Alligators are familiar yet exceptional residents of Louisiana. They have inhabited our wetlands for millions of years, and they are important contributors to the health of those wetlands.  Get a close look at these remarkable North American reptiles while visiting Audubon Zoo or Audubon Aquarium. Don’t miss seeing our rare white alligators as well!

American Alligator Habitat & Range

American alligators, Alligator mississippiensis, live in a variety of freshwater habitats across the southeastern United States. The vast majority live in Louisiana and Florida.

Historic vs. Current Range
American alligators currently occupy their entire historic range, which spans the southeastern United States from Texas to the Carolinas. Louisiana and Florida have the largest populations, estimated at more than 1 million non-hatchling wild alligators each.

Habitat
American alligators inhabit freshwater swamps, lakes, marshes, and streams, as well as brackish water habitats.

American Alligator Behavior

American alligators are social reptiles. They do not nest together or feed cooperatively, but they tolerate living near each other and communicate via body language, bellows, and head-slaps of the water.

Ecosystem Engineers
Alligators are ecosystem engineers in their wetlands habitat. They dig and maintain “alligator ponds” with their snouts. They are constantly moving soil, nutrients, and vegetation around, and this activity improves the quality of habitat for alligators and other wetlands animals.

Basking & Brumating
Like all reptiles, alligators are ectothermic, which means they rely on external heat sources to regulate their internal body temperature. They emerge from the water to bask on logs and on shore, warming themselves in the sunshine. During cold spells, and especially in more northerly parts of their range, they brumate (the reptile equivalent of hibernation) in dens that they excavate. 

Hunting & Feeding
Alligators appear heavy and ungainly on land but can be surprisingly quick over short distances. They really excel in water, though. They are strong swimmers and opportunistic predators that hunt primarily at night. As they grow, the size of their prey increases. Adult alligators feed mainly on fish, turtles, snakes, and small mammals. If big and hungry enough, an alligator might go after larger animals such as deer that come to the water’s edge.

Caring for Young
Unlike most reptiles, female alligators protect their young. After mating with a worthy male (who wins her over by bellowing and fighting off other males), she builds a huge mound nest of vegetation, lays 30-50 eggs, covers them, and then guards her nest for up to two months while the eggs incubate. When ready to hatch out, baby alligators chirp from inside their eggs. Soon, the whole clutch is chirping at mom, and she might break open the nest to help her young emerge. Hatchlings are 6 to 8 inches long and black-and-yellow striped. They make their way to the water quickly, and mom may help by carrying some hatchlings in her mouth.

Year One and Beyond
A female alligator will loosely guard her young for approximately one year, but even with her protection, more than 80% will be gobbled up by other animals. Those that survive the hatchling phase will steadily grow to become dominant apex predators.

American Alligator Conservation

American alligators were trapped and hunted to near extinction but have made a remarkable comeback since the mid-20th century. Louisiana’s alligator management program is recognized internationally as a model for crocodilian conservation success and sustainability.

Threats
American alligators have proven themselves to be extremely resilient animals. As a species, they have been around for at least 150 million years and have survived near-extinction more than once. Individually, alligators that reach a length of four feet or more are threatened only by other alligators, people, and environmental pressures caused by people.

Conservation Efforts
American alligators are a notable conservation success story. For centuries, these reptiles were heavily hunted for their meat and skins. By the 1960s, the species was teetering on the brink of extinction. Once listed as endangered and offered protection, though, alligators began their remarkable comeback. The species is now considered abundant, stable, well protected, and well managed across its range. Successful conservation of alligators has hinged on protecting habitat in state and national parks and preserves; providing economic incentives for private landowners to maintain habitat and coexist with this major reptilian predator; carefully managing existing populations through regulated harvests; and carefully managing human-alligator conflict through public education campaigns and rapid response to “nuisance gators.” .
