AbstractAn observation of the flight of a flock of Common Eiders, Somateria mollisima, on 24 October 2012 suggests that, 15 years after construction of the Confederation Bridge connecting New Brunswick and Prince Edward Island (12.9 km in length over the Northumberland Strait), the bridge may still be a partial barrier to bird flight and possibly migration. Although we believe the Common Eiders we observed intended to fly over or under the bridge, none of the 44 Common Eiders crossed the structure during the observation period.
