I photographed this pair of Trumpeter Swans slowly moving through the shallow waters of Lake Mattamuskeet Wildlife Refuge in eastern North Carolina. The largest of North American waterfowl, it is resident throughout much of its range, but migratory in other parts. Trumpeter Swans form pair bonds when they are three or four years old. The pair stays together throughout the year, moving together in migratory populations. Trumpeters are assumed to mate for life, but some individuals do switch mates over their lifetimes.
