This common darter was sitting on a bridge railing of a pedestrian bridge. Here he is in a pose to fly away, but he stayed.
The darter was not very shy. People where walking past hem at 10cm or so and he just stayed. Luckily this meant he also didn't mind my camera. I happen to have my tripod with me for photographing mushrooms and because this darter stayed so long on the railing I had plenty time to set op my tripod and choosing a good position and a perfect f/11 for the diaphragma. It was also quite impressive to see on the enlarged preview how the darter his air vent opens and closes for breathing just like nostrils.
