Daily Counts
MSRW Raptor Watch Fall 2020
The Mackinac Straits area is a concentration point for migrating birds every spring and fall. In the fall migrants concentrate on Point LaBarbe, Mackinac Co. on the north side of the Straits.
Directions
The primary count location is on Boulevard Dr. Take US 2 west of St. Ignace, just west of I-75, turn south toward the Bridge Overlook Park. Follow the road past the park traveling along the shoreline about 1.5 miles to the open field area in the middle of the end of the point. The counter will be parked along the road.
Mackinac Straits Raptor Watch
Because of its geography, the Straits of Mackinac is one of the best places in the country for studying raptors in both the spring and fall migration seasons. Depending on spring weather conditions, the Mackinac Straits Raptor Watch operates on one of two sites near Mackinaw City, MI that are about a mile apart from each other. In the fall raptor counts are conducted at Point LaBarbe, near Saint Ignace on the north side of the strait. MSRW also counts Waterbirds utilizing the strait as a migration corridor and/or stopover area.
