Song & Call Comparison

A loud, donkey-like braying 'waaah-waaah' — hence its nickname 'jackass penguin'. Also gives softer grunts and contact calls at the colony. Highly vocal on breeding beaches.
Common Blackbird
Arguably Britain's finest songster: rich, flute-like phrases with deep, mellow quality. Sings persistently at dusk. Alarm is a sharp 'chook-chook'. Song includes liquid 'pew' notes.
Geographic Range & Migration
African Penguin

Common Blackbird
Europe, Asia, and North Africa. Introduced to Australia and New Zealand. Northern populations are migratory.
