... within a short period while fasting ashore. During molt, king penguins ( Aptenodytes patagonicus ) lose half of their initial body mass, most importantly their insulating subcutaneous fat and half of their pectoral muscle mass. The latter might challenge their capacity to generate and sustain...

...Anna P. Nesterova; Jules Chiffard; Charline Couchoux; Francesco Bonadonna SUMMARY King penguins ( Aptenodytes patagonicus ) live in large and densely populated colonies, where navigation can be challenging because of the presence of many conspecifics that could obstruct locally available cues. Our...
