Wild Life In my yard

I love to go outside in my personal jungle to see who wants to play. I have many wild life friends like rabbits,squirrels,birds, etc. For some reason when I run out to say hi to them they run from me. I just want to play and wont hurt a fly. The next day they come back and it starts all over again. I guess it is like a one way game of tag or they are afraid of my immense size.
