Why King Cobras Build Bird-Like Nests and Guard Their Eggs
Most snakes lay eggs in places that are already sheltered.
The female King Cobra does something different: she gathers leaves and twigs to make a nest.
She makes a hidden space inside the nest for her eggs.
The leaves can warm up as they decay.
This warmth helps keep the eggs in a suitable environment.
A female may lay between 21 and 40 eggs.
She stays near the nest and protects them until they hatch.
This nest-building and guarding behavior is unusual among snakes.
During breeding season, female King Cobras gather leaves, twigs, and small branches to build a mound.
The mound contains a hidden chamber where the female lays her eggs.
As nest material decomposes, it produces heat that helps insulate the eggs.
Studies of nests in parts of India found internal temperatures around 3°C above the surroundings.
Females lay 21 to 40 eggs and guard the nest until they hatch.
