Project Puffin, begun by the National Audubon Society in 1973, has restored Atlantic Puffins to Seal Island National Wildlife Refuge and established an active breeding colony there containing hundreds of Atlantic Puffins. Terns have also returned to the refuge now that gull control measures have made it possible for them to breed successfully.
Seal Island is closed to the public because the island was formerly used as a bombing range and live ordinance remains in the area. Now, however, anyone can view breeding puffins and terns on live web cams installed on the island. Visit the web cams May through September, when breeding birds are present.
