Short-eared Owls: ringing reveals mysterious migration

09 Dec 2011

A century of Short-eared Owl ringing has shown differences in this species’ migration over space and time, providing clues about population changes. A candidate for red-listing, analyses of ringing recoveries found that owls originating from Scandinavia and Central Europe travelled the furthest on migration, while those from Britain and the North Sea area made the shortest journeys. Distances travelled increased and then fell during the twentieth century. Reduced immigration may have contributed to breeding declines in parts of this species’ range.
