I saw the Snow Geese from the south dike observation platform. They took flight as a flock from somewhere in the middle of the impoundments, flew over and around the observation tower, and finally settled out in the tidal marsh south of the dike. Some of them actually flew back and forth over the tower a few times as they tried to choose a spot in the marsh.
One Blue Goose is in this photo. In addition, some geese appear significantly smaller than others. I am not sure if that is a matter of distance or whether it reflects a real size difference.
