The common perception that possums construct elaborate underground homes is a misunderstanding. While many imagine these marsupials digging tunnels and chambers, their actual living arrangements are quite different. Understanding where possums truly reside reveals their adaptable nature and unique survival strategies.
Do Possums Dig Burrows?
Possums, specifically the Virginia opossum in North America, do not dig their own burrows for shelter. They are opportunistic animals that prefer to utilize existing structures rather than excavating their own dens. While they may occasionally dig shallow holes in search of food like insects or grubs, these are not extensive enough to serve as a primary dwelling. Their physical build, with claws better suited for climbing than for substantial digging, does not equip them for creating complex underground systems. If a possum is observed entering an underground hole, it is almost certainly one dug by another animal.
Natural Possum Shelter
Instead of digging, possums seek out a variety of existing shelters. They frequently inhabit abandoned burrows created by other animals, such as groundhogs, skunks, or foxes. Natural formations like hollow logs, tree cavities, brush piles, and rock crevices also serve as common resting places during the day.
These adaptable creatures readily use human-made structures, including attics, sheds, garages, and spaces under porches or decks. Possums line these chosen dens with materials like dried leaves and grass for comfort and insulation. They often maintain several active dens within their home range, moving between them every few days to avoid predators and maximize safety.
Physical Traits and Lifestyle
The physical characteristics of possums are well-suited for their opportunistic and nomadic lifestyle, rather than for digging. They possess a prehensile tail, flexible and strong, primarily used for grasping branches and providing stability while climbing. This tail also helps them carry nesting materials, though it is not strong enough to support an adult possum hanging. Their hind feet feature an opposable, thumb-like digit, known as a hallux, which significantly aids their ability to grip branches and navigate arboreal environments.
This semi-arboreal nature means they spend much time in trees, foraging and seeking refuge. Possums are nomadic, moving from one temporary shelter to another, often staying in a particular location for only two to three days. They do not hibernate, but during cold weather, they seek more secure, insulated shelters to protect themselves from the elements.
