A clear threat to conservation: using public policy to reduce bird collisions with windows in homes

Over the past 40 years in North America, more than 40 species of migratory birds have seen population declines in excess of 50%. A significant source of migratory bird mortality is collisions with the windows of single and semi-detached homes, which result in an estimated 15.8 million to 30.5 million deaths annually in Canada. The federal government, who has jurisdiction over migratory birds and a legislative obligation to protect them, has not publicly outlined a strategy to address this source of mortality. By conducting a willingness to pay survey, this research seeks to understand how Canadians value reducing bird-window collisions with their homes. Using this data, in combination with elite interviews and a literature review, alternative policies are assessed. It is recommended that the federal government undertake a public information campaign, seek partnerships with municipalities, and assist in the development of bird-friendly design criteria for willing home certification programs.
