At 3:30 p.m. today, over one thousand Common Mergansers were visible from
Brighton Dam, Triadelphia Reservoir.  I counted 500 before I lost track, and
there were easily that many more visible way out, beyond the narrow neck to
the left.  The reason I lost count was an almost full adult Bald Eagle was
trying to catch a merganser dinner.  Another apparently second year Bald
Eagle was perched on a sandbar off the Greenbridge boat launch area.  I saw
no other waterfowl except a few Canada Geese.  There were also a dozen or so
Ring-billed Gulls around.  No sign of the Elvanders' Golden Eagle, but then,
I wasn't looking for it, being unaware of their posting.

Centennial Lake in HowCo is largely frozen, being solid west of the Concession
Stand.  There were several hundreds (thousands?) of Canada Geese, and quite
a few Mallards.  More interesting waterfowl were 61 Ring-necked Ducks,
6 Ruddy Ducks, 4 Hooded Mergansers, 2 Canvasback, and 1 Coot.
