It is possible to refer to a group of snakes as a lair, bed, pit, or nest. The only exception is a group of rattlesnakes, known as a rhumba.
Rarely do snakes occur in groups. Occasionally during the winter, snakes may gather to mate. This behaviour is also prevalent among bats and marmots. Groups of snakes will gather together in a burrow or behind rocks to wait out the winter months, storing their energy until food becomes more available in the spring. Unlike hibernating animals, brumating animals are awake but preserve energy by lying still.
All snakes are carnivores that consume their prey in its whole. Generally speaking, snakes do not forage for food in groups. With the exception of Antarctica, Ireland, and New Zealand, nearly every region on Earth is home to snakes.
