Green iguanas are known to burrow and lay their eggs in the ground, typically in sandy or loose soil. Here are some key points about green iguana burrowing and egg-laying behavior:
Burrowing behavior: Green iguanas may dig burrows in the ground for various purposes, including nesting, escaping extreme weather conditions, hiding from predators, or resting. Burrows are usually shallow, ranging from a few inches to several feet in depth, depending on the iguana’s size and the type of soil. Burrows are often found in sandy areas, riverbanks, or under vegetation.
Nesting behavior: Female green iguanas lay eggs in the burrows they dig. They typically lay a clutch of 20-70 eggs, depending on their size and age. Female iguanas may use the same burrow for multiple nesting seasons, or they may dig new burrows for each nesting season. Green iguanas are known to exhibit communal nesting behavior, with multiple females using the same nesting site.
Egg incubation: After the female lays the eggs in the burrow, she covers them with soil and leaves them to incubate. Green iguana eggs have a long incubation period, typically ranging from 70 to 90 days, depending on the temperature and humidity of the environment. The eggs absorb moisture from the surrounding soil during incubation, which helps them develop.
Hatching: Once the eggs hatch, the baby iguanas, called hatchlings or neonates, dig their way out of the burrow and emerge on the surface. They are usually independent from birth and are capable of finding food and shelter on their own.
Burrow maintenance: Green iguanas may use their burrows for extended periods of time, and they may also modify or expand their burrows as needed. They may dig multiple chambers within the burrow for different purposes, such as nesting, resting, or avoiding predators. They may also use the burrow as a refuge during cool or cold weather, as they are ectothermic animals that rely on external heat sources to regulate their body temperature.
It’s important to note that green iguanas, especially when they dig burrows, can sometimes cause damage to landscapes, gardens, or structures. In some areas, green iguanas are considered invasive species and may be subject to local regulations or control measures. If you encounter green iguanas or their burrows and have concerns, it’s best to consult with local wildlife or pest control experts for appropriate guidance.
