This image was shot under bright overcast conditions. To be honest, I find portraits like these quite boring but I liked the background and the detail on the bill. I was able to get extremely close to the bird and filled the frame. In Photoshop, I cropped the image 16:9 and added canvas to the RHS for composition.
Edit : Corrected the ID to Grey Heron.
