International audience Social thermoregulation is a cooperative strategy in which animals actively aggregate to benefit from thewarmth of conspecifics in response to low ambient temperatures. Emperor penguins, Aptenodytes forsteri,use this behaviour to ensure their survival and reproduction during the Antarctic winter. An emperorpenguin colony consists of a dynamic mosaic of compact zones, the so-called huddles, included in alooser network of individuals. To maximize energy savings, birds should adjust their huddling behaviouraccording to environmental conditions. Here, we examined the dynamics of emperor penguin aggregations,based on photo and video records, in relation to climatic factors. Environmental temperature,wind and solar radiation were the main factors contributing to huddle formation. The analysis of individualmovements showed that birds originating from loose aggregations continually joined huddles.Sometimes, a small number of birds induced a movement that propagated to the entire huddle, causingits breakup within 2 min and releasing birds, which then integrated into looser aggregations.
