After it had gone we carried on walking around the lake area and noticed a couple of pods next to the lake where people were fishing. As we came closer to the pond I spotted the heron wading in the shallow water next to some water lilly pads. I am fairly sure it was the same heron that I'd seen on the lake as this pond was in the general direction it was heading when it flew off before. I again tried to get closer without it seeing me and the trees around the pond gave me a bit of cover.
Just after I took the previous shot it must have seen me and flew off again. When I first looked at the display on the back of my camera I thought I'd got a great shot of it taking off but when I got a closer look I realised the it was mostly blurred. I guess the reason was that it was a bit darker around the pond than by the lake so the shutter speed had dropped to 1/250th of a second and the heron was moving its head, neck and wings too fast. The legs, tail feathers and the back are almost not blurred but I really needed the head to be a lot sharper and I could have got away with the wings been blurred I suppose. I should have aimed to get 1/750th or even 1/1000th of a second on the shutter speed to have got a better shot. I should really have bumped the ISO up to 400 or 800 to achieve the faster shutter speed, so it's a lesson I need to think about more when trying to photograph wildlife (or anything else) which is likely to move fast.
