West Sister Island is Lake Erie's largest sites protecting a rookery for Great Blue Herons, Cormorants, Great Egrets, and Black-crowned Night Herons. The birds must travel eighteen miles round trip to the mainland marshes, where waters are shallow enough to allow the birds to hunt for food for themselves and their young. Public access is not permitted, except for research purposes.
The geology of West Sister Island consists of glacial fill that lies over a limestone shelf. It is jointly owned by the U.S. Fish and Wildlife Service and the U.S. Coast Guard, with refuge management being done by the staff at the Ottawa National Wildlife Refuge, under the Federal Wilderness Act.
