Variation of mutual colour ornaments of king penguins in response to winter resource availability
International audience We studied the influence of marine resources during a year of abundance and another of extreme scarcity, on sexually selected ornaments of the king penguin ( Aptenodytes patagonicus), a seabird with striking coloured ornaments in both sexes. Displaying birds started their bree...
