When it is really hot outside, birds try to avoid direct sunlight, like this Great Blue Heron (Ardea herodias) that I spotted last week during a visit to Occoquan Bay National Wildlife Refuge. The heron was relaxing in the vegetation at the edge of a small pond and appearing to be standing on a single leg, with the other leg probably tucked under.
In the winter months, I often see herons using this position as a way of conserving body heat, which obviously was not needed on this hot, humid day, so I am wondering if the “missing” leg was simply hidden by the vegetation.
