The eurasian eagle-owl

Bubo bubo

The Eurasian eagle-owl is the world’s largest owl. Its sonorous hoot used to be a common sound in large parts of Sweden, but in the middle of the 20th century the number of these owls dropped dramatically. Environmental toxins, reduced number of nests and persecution are thought to be the causes. After transplanting 1000’s of eagle-owls, it is now back.
