Food-caching by arctic foxes (Vulpes lagopus (L., 1758)) is a behavioural adaptation thought to increase winter survival, especially in bird colonies where a large number of eggs can be cached during a short nesting season. In this pa- per, we measured the energy content of greater snow goose (Chen caerulescens atlantica Kennard, 1927) eggs and eval- uated their perishability when cached in tundra soil for a whole summer. We estimated that eggs lost only ~8% of their dry mass over 60 days of… Expand
