Can't a bird take a bath in peace?!
Pools of water in the forest can get quite busy at times with many small songbirds taking the plunge. In this image a blackcap was bathing closer to the camera with a robin behind it. When the robin took off it looks like it's taken the blackcap by surprise judging by the look on its face.
