Size Comparison
Habitat Comparison
African Penguin
Rocky coastlines and offshore islands of southern Africa. Nests in burrows, under boulders, or in surface scrapes.
Downy Woodpecker
Deciduous and mixed forests, orchards, parks, and suburban areas. The most common woodpecker at feeders in North America.
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.
Downy Woodpecker
A sharp 'pik' or 'peek' contact call. Drums on resonant branches with a rapid, light tattoo — softer than larger woodpeckers. Also gives a high descending whinny 'keeer-keeer'.
Geographic Range & Migration
African Penguin
Coastal southwestern Africa from Namibia to Port Elizabeth, South Africa. The only penguin species breeding in Africa.
Downy Woodpecker
North America from Alaska and Canada south through the United States, excluding the arid Southwest.

How to Tell Them Apart
African Penguin
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
Downy Woodpecker
Black and white plumage with a broad white stripe down the back. Black wings with white spots. Males have a small red patch on the nape.
Short, chisel-shaped, dark bill — noticeably shorter than the similar hairy woodpecker
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.
Downy Woodpecker
The downy woodpecker is the smallest and most widespread woodpecker in North America. Its small size allows it to forage on thin branches and weed stems that larger woodpeckers cannot access. Downies often join mixed-species flocks in winter, benefiting from the extra vigilance of multiple species watching for predators.
