Wildlife photography random tip: When you see two animals interacting with each other, zoom in tight. Ideally so tight that you only have the interaction in the frame. In such situations this is all the viewer wants to see so nothing else matters (most of the time).

For example - the background in this picture is distracting. The picture would have be far more impressive without the background.

Sometimes including a bit of the background works or if you just have to, then try to avoid bright highlights in the background. I raised my angle here to avoid a lot of the bright sunny spots in the background grass here.
