A camera trap in a Polish forest has captured first-of-its-kind footage of a family of bison fighting off a pack of wolves.
On September 15 last year,five wolves began hunting the animals – only to be driven off.
The recording shows the pack surrounding a calf,biting its neck and attempting to drag it away before two cows come to the rescue.
The wolves return and seize the calf a second time in the background of the video — however,this time the entire bison herd comes to its defence.
The clip was recorded in the Białowieża Primeval Forest,the oldest and best-preserved temperate lowland forest in Europe,which hosts the world’s largest population of European bison.

It is the first time an incident like this has been captured on camera (Picture: Wijnands & Borowik,/Cover Media)The first confirmed bison kill since reintroduction dates to the mid-1990s,after which wolves appeared to shift their diet towards roe deer (Capreolus capreolus),red deer (Cervus elaphus) and wild boar (Sus scrofa),likely because these species are easier prey than bison.
