A pair of diving ducks on a small, clear water, sand bottomed pond in a wooded area (pines, mature hardwoods). This ID seemed a bit improbable to me, but I can't find anything else that matches. Pretty sure it's a breeding pair; old hollow trees are present nearby so the habitat seems right. No fish in this pond, but excellent water quality, abundant aquatic insects, tadpoles and such. Photos taken with a macro lens, so not too good but probably clear enough for a birder. However, I'm not an expert in birds and given the eclipse plumage here, please don't rely on this proposed ID until confirmed or corrected by an expert.
