There are almost always a few Great Blue Herons (Ardea herodias) at Occoquan Bay National Wildlife Refuge. Most often I see them patiently fishing in the water, but sometimes I have to scan the tangled vegetation surrounding the ponds to find them, as was the case last Friday. Some herons are very skittish and fly away as soon as they sense my presence, but this heron remained in place while I carefully composed this image and continued silently along the trail.
Unlike the Great Egrets, Green Herons, and Ospreys that leave our area in the winter, Great Blue Herons are with us year round. Now that the weather is getting colder and we have already had our first snowfall (it was less than a half-inch (1 cm) or so), I suspect that it is getting harder for herons to find food. I am sure, though, that I will continue to see herons foraging for food, including in the frigid waters of the ponds and the bay—even when the surface of the water freezes, there is enough movement in the water that there are some open areas.
