Keeping up with my Trumpeter Swan theme this week; I made this image in Monticello, Minnesota where the swans congregation by the hundreds each winter. There is a power plant up river keeping the water mostly free of ice. Early mornings are my favorite time of day to photograph swans because of the added fog/mist from the warm water. This is a double edge sword however, the air temp is often below zero.
