觀察細節
Large rafts of common mergansers in reservoir. Migrating. The main raft of birds on the north arm of the lake was estimated to be almost 1 km in length. A road travels along the eastern side of this arm and we were able to travel the entire length of the raft of birds. There were also a group of 100 common Mergansers directly below the dam and another large raft above the dam in the main arm of the lake. I did a very conservative estimate of the total numbers which I estimate were far greater than what I reported. The water level is currently being drawn down.
