Waterbirds Fall 2021
The Mackinac Straits area is a concentration point for migrating birds every spring and fall.
The Waterbird count is conducted from McGulpin Point on the west side of the peninsula and Graham Point on the north side of the Straits on alternate days in 2020. To McGulpin Point: Take Central Ave. west from Mackinaw City to the corner of Headlands Rd., turn north and follow the road to the waters edge to find the Waterbird Counter. Graham Point is at the south end of N. State St. (where the road ends) in St. Ignace.
