My husband,Tom, has always been good with animals, but I was still amazed when he befriended a female grouse(松鸡). It's _11_ for a grouse to have any contact(接触)with people. In fact, they're hard to spot,_12_ they usually fly off when they hear humans approaching. This grouse came into our lives in _13_. Tom was working out in the field when he _14_her walking around at the edge of the field. She was_15_ unafraid and seemed to be _16_ about what he was doing. Tom saw the _17_ bird several times, and she got more comfortable around him. We quickly grew _18_ of the bird and decided to call her Mildred. One day, as Tom was working, Mildred came within a few feet of him to watch. Tom _19_ he didn’t see her and kept working to see what she would do next. Apparently, she didn’t like to be _20_ . She’d run up and peck(啄)at Tom’s hands, then _21_ off to see what he would do. This went on for about 20 minutes, until Mildred became tired of the _22_ and left. As spring went and summer came, Mildred started to _23_ more and more often. _24_ Mildred felt comfortable enough to jump up on Tom’s leg and stay long enough for me to get a _25_ of the two of them together. This friendly grouse soon felt _26_ not just with our family, but with anybody who walked or drove by. When hunting season opened, we put a _27_ at the end of our driveway asking _28_ not to shoot our pet grouse. My father, who lived down the road, _29_ warned people not to shoot her. _30_ , hunters would stop and take pictures, because they had never seen anything like her.
