Habitat Comparison
Shared Habitats
African Penguin only
None
Peregrine Falcon only
African Penguin
Rocky coastlines and offshore islands of southern Africa. Nests in burrows, under boulders, or in surface scrapes.
Peregrine Falcon
Diverse habitats from tundra to tropics, typically near cliffs or tall structures. Increasingly found in cities nesting on skyscrapers and bridges.
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.
Peregrine Falcon
A harsh, wailing 'kak-kak-kak-kak' repeated rapidly in defense of the nest. Alarm call is a long screaming 'raaak'. Mostly silent away from breeding sites.
Geographic Range & Migration
African Penguin
Coastal southwestern Africa from Namibia to Port Elizabeth, South Africa. The only penguin species breeding in Africa.
Peregrine Falcon
One of the most widespread birds, found on every continent except Antarctica. Migratory populations travel vast distances between breeding and wintering grounds.

Black upperparts and white underparts with a distinctive black horseshoe-shaped band across the breast. Pink patches of bare skin above the eyes help with thermoregulation.
Sturdy, pointed, black bill with a grey band near the tip

About These Birds
African Penguin
The African penguin is the only penguin species native to the African continent, also called the jackass penguin for its donkey-like braying call. Their population has plummeted over 95% since pre-industrial times due to egg collection, oil spills, and competition with commercial fisheries for sardine and anchovy stocks.
Peregrine Falcon
The peregrine falcon is the fastest animal on Earth, reaching speeds over 389 km/h during its characteristic hunting stoop. Like the bald eagle, peregrines suffered dramatic declines from DDT but have recovered through intensive conservation programs. They have adapted remarkably well to urban environments.
