Solo the trumpeter swan returns

Solo, the trumpeter swan who's been returning to Turnbull National Wildlife Refuge for at least three and possibly four decades, arrived at Winslow Pool on Jan. 25, 2010, as soon as enough open water was free of ice for him to come back. This time he returned with the mate he found in 2009 and three of the four cygnets they produced that spring. Refuge biologists do not know where the swans spent the ice-up portion of the winter.

The three 7-month-old cygnets tip bottoms up to feed on underwater vegetation as one of their parent trumpeter swans stays vigilant at Turnbull National Wildlife Refuge. There's no way to positively identify the adult as Solo or his female partner without handling the bird and bending back feathers to reveal its sex organs, refuge biologists say. (Rich Landers)
