Habitat Comparison
African Penguin
Rocky coastlines and offshore islands of southern Africa. Nests in burrows, under boulders, or in surface scrapes.
Common Nightingale
Dense thickets, scrub, and undergrowth in deciduous woodland. Prefers areas with thick ground cover near water.
Song & Call Comparison
African Penguin
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 Nightingale
Considered Europe's finest songster: an extraordinarily rich, loud, flute-like melody of bubbling trills, slow whistles, and a distinctive crescendo 'lu-lu-lu'. Sings day and night.
Geographic Range & Migration
African Penguin
Coastal southwestern Africa from Namibia to Port Elizabeth, South Africa. The only penguin species breeding in Africa.
Common Nightingale
Breeds in Europe and western Asia. Winters in sub-Saharan Africa. A long-distance migrant crossing the Sahara.

Sturdy, pointed, black bill with a grey band near the tip
Common Nightingale
Plain warm brown upperparts with a rufous-chestnut tail. Pale greyish-white underparts. Unremarkable appearance belies its remarkable voice.
Thin, pointed, dark brown bill
