I went for a morning swim on Blue Mountain Lake in the heart of the Adirondacks. There were four loons about 40 feet offshore busily diving for fish. One of them came up with a big one, but he or she scampered off out of photo range before I could get a shot. These two were kind enough to pose. I think the four were two adults and two juveniles, and these two are an adult and a juvenile.
