In the deserts gerbils bury tunnels underground that they call 'chambours.' And one gerbil is in charge of that one. Gerbils often group up together to defend each other from predators such as Snakes, Birds probably.
Gerbils live all over the place! There are actually many different species of gerbils. Domesticated gerbils are Mongolian gerbils, which means they are originally from Mongolia. Gerbils are desert animals, so they live in semiarid and arid places, like the deserts of Mongolia.
