觀察細節
Four pairs, mostly resting on the close bank and swimming in the shallow. Watched a pair mate as well. The male was alone for a bit and began calling as it swam down the lake. It continued calling until it found its partner, they swam into open water where the male mounted the female and stayed for a couple seconds until she was completely underwater, after which, they splashed apart. 2 photos of copulation, the rest of normal resting behavior
