A recently released video from a camera trap in Białowieża Primeval Forest in Poland has documented a rare event: a herd of bison defending a calf from a pack of five wolves. Captured on September 15, the footage shows the wolves initially attempting to take the calf, only to be repelled by two adult bison. After a second attempt, the entire herd intervenes to protect the calf, successfully driving off the wolves. This incident marks the first recorded evidence of wolf attacks on European bison in this region, challenging the long-held view that bison have no natural predators aside from humans. The Białowieża Forest is home to the largest population of European bison, which were reintroduced to the area in 1952 after becoming extinct in the wild in 1919.
Why It Matters
The documentation of wolves attacking bison is significant as it provides new insights into predator-prey dynamics within European ecosystems. Historically, wolf attacks on bison were more common in the 19th century, with records indicating around eight bison kills annually in the Białowieża Primeval Forest. However, since the mid-1990s, predation on bison has been rare, as wolves have shifted their focus to more manageable prey like roe deer and wild boar. This shift reflects changes in ecological balance and highlights the ongoing interactions between species in this ancient forest, which has been a protected area since the 14th century.
