Researchers captured rare camera-trap footage in Białowieża Primaeval Forest in Poland showing wolves hunting European bison, Europe's largest land animal. The video documentation challenges the assumption that mature bison face minimal predation risk in their natural habitat.
European bison, weighing up to 900 kilograms, have long been considered largely safe from predators due to their size and strength. Wildlife managers have generally assumed that only calves remain vulnerable to wolf attacks. The new footage from Białowieża, one of Europe's last primeval forests straddling the Poland-Belarus border, demonstrates that wolves target adult bison as well.
The camera-trap recording marks a significant behavioral observation in a region where both species have been reintroduced after near extinction. European bison disappeared from the wild by 1919 but were restored through a captive breeding program beginning in 1952. Wolf populations similarly vanished from much of Western Europe before recent natural recolonization from Eastern Europe.
This hunting behavior has ecological implications for understanding predator-prey dynamics in rewilding ecosystems. As apex predators like wolves return to European forests, their interactions with large herbivores reshape forest structure and composition. Bison killed by wolves provide carrion for scavengers, affecting nutrient cycling and biodiversity across the food web.
The footage provides direct visual evidence of predation rates and hunting strategies that were previously difficult to document. Scientists studying Białowieża can now refine models of how wolf and bison populations regulate each other. Understanding these interactions proves essential for managing reintroduction programs and predicting ecosystem responses as large carnivores reclaim their historical ranges.
The observation underscores how European wilderness areas continue revealing gaps in scientific knowledge about animal behavior. As remote camera technology improves and protected forests expand, researchers gain unprecedented insight into predator-prey relationships that shaped European
