How to Identify African Penguin

To identify African Penguin (Spheniscus demersus), look at these key features.

Physical Characteristics

Body shape

torpedo

Coloration

Distinctive black dorsal plumage and white ventral plumage, with a prominent black band across the chest and a white stripe extending from above the eye to the chin. Pink glands above the eyes are visible, especially when the bird is warm.

Scale type

none

Mouth position

terminal

Distinctive features

Black facial mask with a white stripe extending from above the eye to the chin, Black band across the chest, Pink supraorbital glands for thermoregulation, Strong, paddle-like flippers for swimming, Short, stiff tail feathers

Dorsal fin

Not applicable; birds have wings modified into flippers.

Tail fin

Short, stiff tail feathers used for balance on land and as a rudder in water.

Pectoral fin

Highly modified into powerful, flattened flippers for propulsion through water.

Distinctive fins

Wings are modified into rigid, paddle-like flippers, providing exceptional hydrodynamic efficiency for underwater 'flight'.

Identification Tips

1. 1

   Plumage Pattern

   Look for the distinct black and white pattern, especially the black band across the chest and the white stripe above the eye extending to the chin. This differentiates it from other penguin species.

2. 2

   Facial Glands

   Observe the pink glands above the eyes. These become more prominent and pinker when the bird is hot, aiding in identification and indicating its thermoregulatory state.

3. 3

   Vocalization

   Listen for its characteristic donkey-like braying call, which gives it the alternative name 'Jackass Penguin'.

4. 4

   Size

   Adults typically stand 60-70 cm (24-28 inches) tall and weigh 2.1-3.7 kg (4.6-8.2 lbs). This size helps distinguish it from larger or smaller penguin species in its range (though no other penguin species naturally occurs in its range).
