Identification

How to recognize adelie penguin

Use several field marks together. Apparent color, scale, and proportions can change with depth, visibility, lighting, age, posture, and viewing angle.

Life stage and viewing conditionsCompare several marks together. Age, sex, lighting and posture can change the appearance; a regional card is not a checklist for every site.

Behavior

What divers may observe

Behavior changes with location, season, life stage, food, reproductive activity, environmental conditions, and human presence.

Observation 1It swims underwater to pursue prey and can travel substantial distances over ice.Observation 2It breeds on exposed coastal ground during the Antarctic summer.

Habitat and range

Where this species lives

Around Antarctica and nearby islands.

Antarctic coastal seas, sea-ice margins and exposed rocky nesting ground.

Habitat note 1

Range: Around Antarctica and nearby islands.

Habitat note 3

The regional cards provide starting points for identification. Local depth, season, access and presence must be confirmed before planning an encounter.

Responsible encounters

Observe without changing the animal's behavior

Conditions and local regulations take priority. Follow the operator's briefing, maintain control, and allow wildlife to choose distance and direction.

Protect nesting and resting birdsView from established paths, hides or a quiet boat position. Stay clear of nests, burrows, roosts and routes to the water.
Allow natural feedingDo not feed, pursue or deliberately flush birds. Keep pets and bright lights away from breeding colonies.
Follow the local approach rulesUse binoculars or a longer lens instead of moving closer. Respect seasonal closures and current wildlife-distance rules.
Species-specific careAvoid blocking travel routes between colonies and the sea.

Conservation note 1

Least Concern (LC). Global assessment in the IUCN-linked GBIF record checked 29 October 2026; local populations and protections can differ.

Conservation note 2

Local conservation checks should include habitat condition, water quality and any restrictions on collection or disturbance. A global category is not a local abundance estimate.

Conservation note 3

Protect the habitat described above and follow current protection, approach and biosecurity rules at the destination.
