This was a very rare bird for our area and birders were coming from all over to add it to their life list. The day I got to see it was overcast with fog. The conditions made all my shots look like black & white. Prior to this, the bird had been so far out on the lake that only spotter scopes could be used. Finally it was much closer. In winter plumage, in summer breeding plumage it actually does have a red throat but kind of nondescript in winter.
