Introduction

Can you imagine being here in Yellowstone at dawn on a quiet morning? You've tramped through a new snowfall and now you wait upon a lonely ridge. And suddenly, you hear it—a cry that echoes across the valley and tingles your spine.

Perhaps he is right, but, today, let's start by learning a bit more about this fascinating animal, the gray wolf (Canus lupus).
