Migratory Birds Convention Series: The Mountain Bluebird
While one country's list of protected species may differ from the other, most of Canada's bird species are protected under the provisions of the treaty and the MBCA. The beautiful mountain bluebird (Sialia currucoides) featured on your coin enjoys a migratory range that stretches from Canada to Mexico; as such, it is protected both in Canada and the United States under the terms of the treaty, and by federal law.
