Data range from 25 October 2010 to 15 March 2011, when the only substantial food source on the sea ice is carrion. Foxes that were present at hotspots are shown in the top half of the table, followed by those that were not. F females, M males
^aindicates individuals for which the first presence on the sea ice was a visit to a hotspot
