Walking along the canal, I observed the heron intensely peering into the water, looking out for fish to pounce on. Photo taken with a tamron 600mm lense. It was a beautiful sunny Easter Monday all day, with many families & dog walkers out in in force. Plenty of narrow boats plying up and down the canal. The heron remained in its position for a considerable time, providing excellent photo opportunities for all. A totally enjoyable & worth-while day, with my wife by my side too...and she loved it too!
