I found a low level platform in front of it and got into position. It soon was diving and catching fish regularly right in front of me. I was at a really awkward angle and so I was not able to hold the lens very well however I am pleased with the results.
I am hoping to return to the site soon (ish) to photograph the female with cubs that has been reported in the area.
Here are two images, I will upload some more over the next few days.
