Historical photo of Trumpeter Swans from 1981 at Big Lake near Mt. Vernon, WA. At that time about 400 Trumpeter Swans wintered in this area with about an equal number of Tundra Swans. Now there are about 9,000 swans in this same area. A testament to collaborative work with government agencies, farmers, citizens and nongovernmental organizations like NWSCA.
