Would-be Fisherman

Bird photography is not my usual thing.
But this little Cape Wagtail spent some hours today at the side of the pond tracking the fish and looking for all the world like he was about to dive in.
Just to be clear they don't usually fish (that I know of and I looked it up), so it was curious. They eat insects.
Maybe he thought that pioneering a new food source would be evolutionarily helpful. Or maybe he was just trying to annoy the fish.
Either way, after some to-ing and fro-ing he needed a little leg stretch.
