(courting pair)
观察细节
(one female was doing a variety of strange things which were presumably courtship signals, such as diving deep under water in a vigorous lunge several times then lying as flat as possible on the surface of the water. One male was quite interested but seemed to miss his cue. Later two drakes were fighting amongst themselves and with the female and nothing got accomplished!)
