High-Tech Tracking Reveals ‘Whole New Secret World of Birds’

Smithsonian shares the new study published in Current Biology from their own Nathan Cooper, a behavioral ecologist of the Smithsonian Migratory Bird Center.

Once the birds arrived in Michigan, many of them started making long trips to different spots within the breeding area. The trips ranged anywhere from three to 48 miles, and most of the traveling birds were those that weren’t breeding that season. What could they be up to?
