Île aux Cochons, or Pig Island, is a small, uninhabited island located in the Saint Lawrence River in Canada. It is part of the Biodiversity Reserve of the Thousand Islands and is known for its unique ecosystem and diverse wildlife. The island is primarily covered in dense forests and offers a habitat for various bird species. The name "Île aux Cochons" originates from the historical presence of feral pigs on the island. Although the pigs are no longer found there, the island remains a point of interest for nature enthusiasts and researchers studying the region's flora and fauna.
