Observation details

Languid wing strokes, sudden turns, and intermittent plunges to the water. Black body and face, dark gray wings. Lighter vent. Failed to have my good camera with me today! Tried to get a snapshot by holding iPhone up to my binoculars. Here is about the best of the marginal photos this effort generated.
