This buck looks as if he is leading an easy life, resting in the meadow surrounded by tasty grass. But this is not the typical pose of the deer on my property. Most of the time deer are on the move or standing up to eat. At any movement from me, their muscles tense. If I look hard in their direction, they run.
After so many years here, I had hoped they would get used to me. But they haven't. If they aren't running from fear, I often find them sparring with each other or vigorously running back and forth across the field as if exercising to keep strong. They do have to worry about mountain lions. Even though mountain lions have a large range, and are killing only what they need, the deer know that the lions can come after them at any time. Once in awhile I find a bone or two as evidence of a meal past.
