I have never seen that before. She must be very comfortable that you are not going to harm her. I had a hummingbird feeder on the side of my porch. One day I was sitting in my big green chair in front of the sliding glass door when one of the hummers came up to the door and fluttered there for a few minutes. I was startled, then it came to the door again. I when out on the porch to see what was going on and found that the feeder was empty. I truly think the hummer was telling me to get off my tush and fill up the feeder. I was very careful to keep it filled up after that!
