觀察細節
2 drakes with dark heads, bright white flanks, 2 hens darker overall with small white patches around the base of the bill. Spent most of this observation period floating lazily on the Jersey side of the river. Saw them pick up and resettle only once. Wasn't sure about Greater/Lesser in the field, but in-flight photos show wing stripes that have a distinct transition from white to gray around the start of the primaries.
