For the past 2 days, I have seen 6 loons at the University of Richmond lake. I thought they "must be" common loons, but they reminded me of a merganser and I noticed some brownish red on their necks. They kept diving and I didn't get great looks either time, plus I didn't have my binoculars or field guide. If anyone one is over in the area, would you see if those are common loons or red-throated loons. There might be some of each too, since there were 6 birds. The bills looked whitish too, and other field marks threw me off, but I am leaning towards red-throated loons. Leeanna
