In 2009, the State of Maine supported 4,070 pairs of Arctic terns, nesting on 10 islands. Arctic terns travel an amazing distance during their annual migration. Each year the birds leave their nesting islands in Maine, fly across the Atlantic Ocean, travel south to Africa, and spend much of the winter feeding along the Antarctic coastline before heading north to start the breeding season in May and June. We estimate this to be an annual migration of over 28,000 miles.
The oldest known Arctic tern is a 34 year-old Petit Manan Island bird!!
