Date of disappearance: 1916
Reason: Egg collecting. Persecution.
Special powers: In Finland, recovering populations of white-tailed eagles have reduced the range of invasive North American mink. Mink are highly vulnerable to attack from above: these massive eagles will pick them off the surface of the water. This could have a major protective effect for the many species that mink eat.
Status: The sea eagle was reintroduced to Rum in 1975 and has spread along the west coast of Scotland. Attempts to reintroduce it into England have so far failed for political reasons.
