Deepak says moving the bird to the left..What he actually means is moving your camera to the right/swing your camera to the right or move yourself to a step to the right.

While cropping during post processing this thought comes up that you move your subject in the frame. In photography - for some it might be just play of words, but nevertheless it is an important thought process - one doesn't move the bird/animal. One re positions himself/herself. When we close our eyes and think, then we realise as human beings we are too small in front of nature. Though we have been spoiling/manipulating and exploiting it.
