Another flew by at the other end of the parking lot a minute later.
Found these two subadults in duff of a drainage ditch within the high water range of a vey small cypress pond with about 5-7 mature cypress trees. This is between the highway and a large area of managed Longleaf Pine on the Holly Shelter Game Land.
