The American beaver (A. canadensis) is a large, semi-aquatic rodent known for its flat, paddle-shaped tail and webbed hind feet. Beavers are industrious builders, creating dams and lodges from wood and mud. They play a crucial role in ecosystem engineering, creating wetlands that support biodiversity.

A. canadensis, commonly known as the Canada Goose, is native to North America. It is widely distributed across Canada and the northern United States. Its range extends from the Arctic and subarctic regions in the north to the temperate zones of the United States in the south.

Canada Geese inhabit a variety of environments, often near water bodies such as lakes, rivers, marshes, and estuaries. They are adaptable birds that can also be found in urban and suburban areas, including parks and golf courses. The climate they thrive in ranges from cold arctic tundra to temperate zones, with seasonal migrations to warmer regions during winter.

Canada Geese occupy a niche as herbivorous grazers and are often found in large flocks. They feed on grasses, sedges, grains, and aquatic plants. Their presence in diverse habitats allows them to play a role in seed dispersal and as prey for larger predators. The geese have adapted to various habitats, which include nesting on elevated sites such as cliffs or rooftops in urban areas, showcasing their adaptability.
