winter sunset on the big pond

Another very chilly day. The day was ~10-25*F. Fortunately less wind than yesterday. Lots of birds were on the big pond (Fresh Pond in Cambridge). The ones I saw:
20 Canvas back ducks
20 Ring necked ducks
50 Canada geese
a pair of bufflehead ducks
maybe a male wood duck?
lots of sea gulls
a few robins
and a Coopers hawk eating his dinner
