It was very foggy yesterday. On my way to Edwin B Forsythe National Wildlife Refuge I could see no more than 100 ft (30 m) ahead, and twice almost ran into deer crosssing the road! When I arrived at the refuge, the usual scenery looked very iffy in the thick fog, but I was not about to go back after a two-hour drive.
Slowly the fog lifted, and after half an hour, sunlight fell on beautiful swans and other birds swimming in the sweet water pond. The swans were probably the same I photographed last week, but they had lost their juvenile colors and were all white. They had been preening and looked much cleaner than last week.
The following photos show a Mute Swan flapping its wings after it had finished preening and taken a dip in the water.
