Mature female
alligators move from interior marshes to open deep-water areas
during the spring to mate. Immature alligators and mature male
alligators tend to remain in these open deep-water area year
around. After mating, females return to the interior marsh in
search of isolated ponds. These areas usually have dense
vegetation adjacent to the isolated ponds, which will be used for
nest construction. Female alligators generally build their nests
by pulling vegetation together forming a mound. This mound nest
will be 2' – 4' high and 4' – 8' in diameter. The female alligator
makes a cavity by opening the nest and lays 20-50 eggs (averaging
35 eggs). After all the eggs have been laid, the female covers the
cavity containing the eggs with vegetation from the nest. The nest
vegetation maintains suitable temperature and humidity, which
incubates the eggs. The female will remain near the nest during
incubation and must open the nest to help the young alligators
(hatchling) exit the nest. Approximately 65 days after the eggs
have been laid; the young will begin hatching and calling. Upon
hearing the calls of the young, the female alligator will help
them exit the nest by opening the top of the nest. The young may
stay near the nest site for a couple of years. During the winter
alligators will enter underground holes and remain dormant. As
spring arrives, alligators emerge from winter dormancy and the
annual processes (mating, nesting, wither dormancy, etc.) begin
again.
