Adélie penguins feed both by predation and foraging, diving into icy Antarctic waters.
Primary Diet:
-
Krill (main component)
-
Fish
-
Squid (occasionally)
Feeding Style:

They dive up to 150–175 meters, usually for 2–5 minutes.
-
Agile swimmers capable of reaching speeds of 5–8 km/h.
-
They catch prey with their beaks, often hunting in groups.
🪺 Breeding & Life Cycle
-
Breeding colonies contain thousands to hundreds of thousands of penguins.
-
They migrate long distances (~13,000 km/year) between feeding grounds and nesting areas.
Nesting:
-
Build nests from stones on ice-free land.
-
Males collect stones to attract females.
Breeding Facts:
-
Lay two eggs per season.
-
Both parents incubate eggs for ~32–34 days.
-
Chicks fledge after about 50–60 days.

Population: ~10 million individuals
-
Some colonies are stable, but others face pressure.
Threats:
-
Climate change affecting sea ice
-
Changes in krill populations
