Sheep herd plunder and pillage middle Himalayan hills on their winter migration, ruining undergrowth

A large sheep herd plunders and pillages the middle Himalayan hills during its winter migration, damaging the undergrowth. The herd, brought into the forest by shepherds, raids the forest cover and crushes the undergrowth with massive, sudden pressure. Some of the young sheep hump each other while others head‑butt.
