An observation of the spring 2006 migration of Black Scoter Melanitta nigra, in Northumberland Strait, interrupted by the Confederation Bridge, New Brunswick - Prince Edward Island

摘要

An observation from the bridge of a flock of Black Scoters suggests that, nine years after construction, the 12.9 km Confederation Bridge may still be a partial barrier to bird migration. Only 3 of 18 scoters (16.7%) crossed over the structure during the observation period.
