The first details of the migration pattern of a male Ring Ouzel T
urdus torquatus, fitted with a geolocator on its Scottish breeding grounds, showed that it wintered in the Algerian Atlas Mountains, substantially east of the suspected main wintering area.

Median autumn stopover and wintering areas (ellipses) identified from geolocations from an ouzel tracked from Scotland, and recovery locations of British-ringed ouzels. Stopover and winter location ellipses represent the standard deviation of locations around the median point. British-breeding ouzels recovered in autumn (September–November: stars), winter (December–February: open circles) or spring (March–April: upward triangles) are shown alongside non British-breeding ouzels recovered during September–ovember (filled circles). http://dx.doi.org/10.1080/00063657.2015.1077779
