Cuckoo reptile

Duration: 01:53

A monitor lizard eats the eggs of a Nicobar megapode. Then, like a cuckoo, it lays its own eggs in the bird's nest mound, and the unwitting birds look after them until they hatch, keeping the mound at the right temperature to incubate the eggs. Baby monitor lizards hatch out inside the mound, and dig their way out.
