What specific body part does the wood bison employ to clear deep snowdrifts for forage access in winter?

Answer

Massive head and powerful neck muscles

A key adaptation for surviving harsh northern winters, where deep snow blocks access to preferred forage, is the specialized method of snow removal employed by the wood bison. Unlike many ungulates that use their feet for pawing, the wood bison utilizes its massive head combined with strong, complex musculature in the neck area to execute powerful, sweeping motions. This physical action is specifically designed to push aside deep snowdrifts, revealing the buried grasses and sedges underneath. Furthermore, the forward-reaching hump structure on its back is supported by ligaments and muscles that facilitate this dedicated sweeping motion, underscoring the biomechanical investment in this foraging technique.
