Timber-Wolf
A wolf species in the Canidae family is the timber wolf. North America is the home of this species. Eastern North America has been home to it since the Pleistocene. It appears to be closely related to the red wolf.
Badgers are not typically killed by timber wolves. In circumstances and locations when the other prey animals are scarce, they eat the latter. When badgers go far from their burrows, wolves typically prey on them. This predator (timber wolf) may also kill them at their setts when they are reproducing.
At a sett, Timber-Wolves wait for the badger before striking quickly. In these situations, the badger has no chance to flee and is typically killed. However, this might not always be the case. When an adult badger and a young wolf are involved, the badger might hang in there and not run away.
A young wolf wouldn't attack the badger or risk getting hurt even if it came close to it. Additionally, a severe wound in warm weather might be lethal for the wolf.
