Wombats dig burrows and are pretty much dexterous at it. Their burrows are very technically dug and are about 10 to 100 feet long. Their burrows are about 20 inches wide and may accommodate a wombat easily, giving them enough room to turn around as well.
How they build these burrows
Wombats use their front claws to dig the burrows. The hind feet are then used to push the loose soil backward. Hindrances in the burrows like roots etc are removed by their incisors. Being adroit at this job, they dig their burrows hastily.
Purposes of their Burrows:
Short burrows, usually about 6 feet long, are used to hide or evade.
Long burrows are used for sleeping purposes. The sleeping chamber is situated 6 – 12 meters away from the entrance of the burrows and is at a higher level than the entrance. These burrows are technically built with many entrances and side tunnels.
A burrow is built so that it gives protection against warm weather in warm season and against cold weather in cold season. The burrows also have a controlled temperature and oxygen level.
Most of the time of the wombats in summers is spent inside the burrows to get rid of the heat. Moreover, in summers wombats dig a depression beside the tree trunk to rest in the shade. The burrows are fire proof as well.
Common wombats dig simple burrows with usually one entrance as they prefer to live alone. On the other hand hairy-nosed wombats have burrows with side channels and many entrances.
