觀察細節
One male, 2 females. They stayed close together, unlike the mergansers, who would tend to go off on their own for a while, then re-join their group. The longtails always huddled close together. When they were feeding, they all dived under together, as a group, and re-surfaced together, as a group, unlike the mergansers. I timed two of their dives with a stopwatch; 43 seconds, and 47 seconds. They generally re-surfaced very close to the same area where they started their dive from.
