Pacific Coast Population

More than half of all continental Trumpeter Swans nest, breed, or winter in the Pacific Coast Population (PCP). In 2010, there were nearly 26,800 Trumpeter swans in the PCP, with 95% in Alaska and 5% in western Yukon and northwestern British Columbia. Most of these swans winter in Washington and British Columbia.

The major threats facing Trumpeter Swans in the PCP are:

  • The continuing loss of winter habitat due to
    • Pollution and the conversion of freshwater and saltwater areas to development and housing.
    • Loss of "waterfowl friendly" cropland and a reduction in agricultural crop residues useful to wintering swans.
  • Growing loss of nesting habitat in Alaska to recreation, farming, mining, drilling and harvesting of natural resources.
  • The impact of climate change on important Alaskan nesting and breeding grounds as interior wetlands dry and permafrost disappears.
  • Continuing mortality threats of lead poisoning and powerline collisions.

TTSS is committed to addressing these important issues. We need your help.

The loss of quality wintering habitat is one of the most critical and immediate challenges facing the Pacific Coast Population. We have identified important wintering sites and habitat protection strategies. With your support, TTSS can continue working diligently and cooperatively with stakeholders such as farmers, dairymen, agencies, and conservation groups to secure and protect quality wintering swan habitat.

TTSS has a long history and commitment to addressing lead poisoning in the region. We strongly encourage hunters and anglers to switch to nonlead, nontoxic ammunition and fishing equipment. Help "Get the Lead Out." TTSS is also committed to working with utilities to reduce the number of bird collisions with powerlines. Your support makes that possible.
