Beaver Island has a new tool to help scientists understand the movements of migratory wildlife. On August 16th, the Mackinac Straits Raptor Watch installed a wildlife tracking antenna at the Little Sand Bay Nature Preserve, adding Beaver Island to an international research effort.
Part of the Global Motus Network
The antenna is part of the Motus Wildlife Tracking System, a worldwide network of automated radio telemetry stations. The system is designed to track small animals fitted with lightweight radio tags, including birds, bats, and even large insects.
The new Beaver Island station can detect tagged wildlife from up to ten miles away. Each time a tagged animal passes through the coverage area, the antenna automatically records its identity, time, and direction of travel. By combining this information with data from hundreds of other Motus stations across North America and beyond, researchers can piece together detailed maps of migration routes and habitat use.
Why It Matters
The Great Lakes region is a critical flyway for migratory birds, many of which pass over or stop at Beaver Island during their journeys. Tracking their movements helps conservationists answer questions like:
- Which stopover habitats are most important?
- How do weather patterns affect migration?
- What challenges do birds face as they move between summer and winter ranges?
This knowledge is key to shaping effective conservation strategies — from protecting important habitats to understanding how climate change and development affect wildlife.
Community Support
The project was made possible through a partnership that included:
- Little Traverse Conservancy, which manages the Little Sand Bay Preserve
- Beaver Island Association, providing local coordination and support
- Community volunteers, who assisted with site preparation and installation
Since the preserve has no utility hookups, the system is powered entirely by solar panels, ensuring sustainable operation in a remote setting.
A New Window Into Migration
For Beaver Island, the installation represents a significant step in connecting local conservation with global science. Each detection from the antenna contributes to a shared dataset used by researchers worldwide, making the island part of a broader network working to protect migratory species.
