英语听力：自然百科 秋日黄石公园 Autumn—19（在线收听） |
But now, the final act of the season is about to take place. From out of apparently nowhere come the bighorn sheep, the toughest of all Yellowstone’s animals. They can stay here all winter on slopes and crags that the biting wind keeps clear of snow. Now they are coming together to rut.
Like elk, the males battle for females, but where elk do their best to avoid fights, bighorn relish them. A quick test of horn size and of other important bits of anatomy, and the males get straight to the point of sorting out who is toughest.
As the sound of their battles echoes across the Yellowstone wilderness, it marks the end of autumn. Now the great change is coming again — winter is here.
