What to know about Adélie penguins use colony cues to switch foraging sites if their previous trip was unsuccessful

Researchers tracked Adélie penguins in Antarctica to determine how they select foraging sites. The study found that penguins often use personal experience to return to successful sites, but switch to social information gathered from group travel after an unsuccessful foraging trip.

What happened

Adélie penguins use colony cues to switch foraging sites if their previous trip was unsuccessful Sadie Harley Scientific Editor Robert Egan Associate Editor Many animals live in groups.

Why it matters

Among seabirds in particular, most species form colonies during the breeding season.

Common ground

Although coloniality entails costs, such as increased competition for food and disease transmission, its repeated evolution across animal lineages suggests that group living provides important benefits.

Perspective signals

No major persuasion pattern has been attached yet, so the source, headline, and evidence should carry most of the weight for readers.
