Development of foraging behaviour and evidence of extended parental care in the gentoo penguin (Pygoscelis papua)
of gentoo penguin chicks during their “fledging period”; defined as the time between a chick’s first trip ... their first trip to sea at a mean age of 70 days of age, before finally departing the colony at an average age ... of 82 days. During this fledging period, individual chicks made an average of five trips to sea. Trip ... duration increased significantly with chick age as trips to sea becoming more similar to adult foraging ...
