Gravel Island National Wildlife Refuge
Gravel Island National Wildlife Refuge is a National Wildlife Refuge located off the Door Peninsula in Wisconsin. Founded in 1913, the refuge consists of two Lake Michigan islands that act as nesting grounds for native bird species. It is inhabited by large colonies of shore birds and waterfowl in addition to hosting a pair of great black-backed gulls, one of farthest westward breeding sites of the species.
