The Michigan Department of Transportation noted that two peregrine falcons returned to the Sault Ste. Marie International Bridge this spring, with the pair successfully hatching two chicks in a nest box on the Canadian side of the structure.

Nest boxes for the peregrines have been installed on both the American and Canadian sides of the bridge since 2010, placed at locations that demonstrated past nesting activity.
In 2025, the resident pair of peregrine falcons hatched three chicks in the box on the U.S. side of the bridge. Over the years, the site has been a great success, hatching 47 falcon chicks since International Bridge Administration or IBA staff started counting the birds, Michigan DOT noted in a statement.
Several years ago, the IBA added a video camera trained on the nest box, dubbed the “FalCam.” The popular live video stream – available at www.saultbridge.com/falcam-canadian-nest-box/ – offers bird watchers a close-up look at the seasonal activities of the falcons, which are also known as “raptors.” The best time to view the birds is when they’re nesting in the spring, Michigan DOT noted.
While the peregrine falcon has been removed from the federal endangered species list, it is still listed as a threatened species in Michigan – and thus remains protected by state and federal law. In Canada, the species is designated “not at risk” at the federal level, except for one subspecies listed as of “special concern.”
