More than half of all North American Trumpeter Swans nest, breed, or winter in this geographic area. In 2010, there were about 26,800 Trumpeter Swans in the PCP. Most of these swans winter in western Washington and outhern British Columbia. A few move south in western Oregon or stay a bit farther north in southern Alaska. They migrate north each spring and 95% breed in Alaska, the rest in western Yukon and northwestern British Columbia.
STATUS – Trumpeter Swans
The most recent PCP survey on the Alaska breeding grounds during 2010 found 26,730 Trumpeter Swans: 20,779 adults and 6,011 cygnets. The new 2015 census will be available in mid2016. The mid-winter western Washington Trumpeter Swan Survey showed no increase in the number of wintering Trumpeter Swans. about the same number of The total swans counted in summer 2010 included 25,347 in Alaska and 1,443 in western Yukon and northwestern British Columbia. The PCP increased by 5.5% per year from 1968-2005, and 1.5% per year from 2005-2010. PCP swans winter primarily in southern British Columbia and northwest Washington, with a few in western Oregon, and occasional birds migrating to California and as far east as eastern Idaho.
The major threats facing Trumpeter Swans in the PCP are:
Mortality from lead poisoning caused by ingesting lead shot on wintering areas in both western Washington and British Columbia Mortality from collisions with power lines The increasing importance of agricultural areas has allowed swans to move into new geographic areas, especially where there are dairy farms in western Washington. This has resulted in both a boon for wintering swans in terms of food resources as well as conflicts because in some areas where swans can damage fields during their foraging activities, especially for potatoes and pasture or cover crop grasses. The conversion of waterfowl friendly farming to berry, apple and other types of crops creates a net loss of areas for waterfowl to feed. The impact of climate change on important Alaskan nesting and breeding grounds as interior wetlands dry and permafrost disappears.
ACTION: NWSCA is committed to addressing these important issues. NWSCA’s staff and volunteers have a long history and commitment to addressing lead poisoning in the region.
We are a long time member of the international team working to bring an end to lead shot ingestion by swans in this northwest area. We strongly encourage hunters and anglers to switch to non-lead, nontoxic ammunition and fishing gear. Help “Get the Lead Out”.
Partnership with power companies to reduce power line collisions by swans. This includes both private and publically owned power companies. Swan Safe Power Lines is a common goal, it saves swans and reduces costs for the companies with fewer power outages.
The Northwest Swan Conservation Association is committed to the conservation of our native swans, both Trumpeter and Tundra, in Washington State and around the northwest region.
