I was shocked as I drove along a road near my house and saw upwards of 40 large nests up in the trees. These blue herons had been nesting in the trees for several years and I had never spotted them before. Just before the leaves bud, there is a small amount of time to spot these large, beautiful birds as they are preparing their nest for laying eggs. I sat for quite a while listening and watching their behaviour. It would be easy to pretend you are sitting in a different era while listening to their prehistoric sounding calls and watching their large, graceful movements.
