Incubation sites, also known as nests, are places where eggs are laid and hatched. They provide a safe environment for the eggs to develop until they are ready to hatch. Incubation sites can be found in a variety of places, including trees, caves, and even on the ground. Nests are often made from materials such as twigs, leaves, and grasses, and are usually lined with feathers or fur. The temperature and humidity of the nest must be carefully monitored to ensure the eggs are kept at the right temperature for successful hatching.
