This high, rocky islet is located 32 kilometers northeast of Grosse Île Island on the route of ships entering the Gulf of St. Lawrence. This islet is home to several colonies of seabirds: petrels, northern gannets, razorbills, murres and gulls. The Rocher aux Oiseaux was declared a bird sanctuary in 1919 and, although almost inaccessible, it remains one of the Mecca of ornithology in the Gulf of St. Lawrence.
Today, only the lighthouse built in 1967 remains on the rock. The other buildings such as the lighthouse keeper's house and other outbuildings were dismantled in 2020. Due to its isolation and the mystery it arouses, the rocky island continues to sprouse the collective imagination.
