What is the Detroit River International Wildlife Refuge?
Calf Island became part of the Detroit River International Wildlife Refuge in 2002. This refuge is a special area set aside to protect wildlife. It's unique because it stretches across both the United States and Canada.
Why is Calf Island important for wildlife?
Even though Calf Island is small, it's a very important home for many animals. The Michigan Department of Natural Resources and the Ontario Ministry of Natural Resources have found over 29 different kinds of waterfowl (like ducks and geese) and 65 types of fish living in and around the island's waters.
Nesting spot for herons
Calf Island is also a nesting place for a small number of herons. Herons are large wading birds with long legs and necks. They build their nests on the island, raising their young in this safe environment.
How is Calf Island protected?
Calf Island is the smallest piece of land added to the Detroit River International Wildlife Refuge. Because it's part of the refuge, it remains mostly untouched by people. This helps keep it a quiet and safe place for the wildlife that depends on it.
