Habitat Comparison
Atlantic Puffin
Breeds on grassy cliff tops and offshore islands. Spends winter entirely at sea in the North Atlantic.
Common Raven
Diverse habitats from Arctic tundra to deserts, mountains, forests, and coastlines. Avoids dense urban areas but thrives near human activity.
Song & Call Comparison
Atlantic Puffin
At burrow gives a low, moaning 'arr-arr-arr' growl. Silent at sea. At breeding colonies produces a series of grunting croaks. Chicks give soft peeping calls.
Common Raven
Highly varied: deep resonant 'kraa-kraa-kraa', hollow 'tok-tok', liquid 'klonk', and wing-whooshing. Among the most intelligent corvid callers; uses calls contextually in groups.
Geographic Range & Migration
Atlantic Puffin
North Atlantic from eastern Canada and northeastern United States to Iceland, Norway, and northwest Russia.
Common Raven
Holarctic distribution across North America, Europe, Asia, and North Africa. The most widely distributed corvid.

How to Tell Them Apart
Atlantic Puffin
Black upperparts and white underparts with a distinctive white face. In breeding season, the face brightens and colourful bill plates develop. Winter plumage is duller with a darker face.
Large, laterally compressed, triangular bill — bright orange, blue, and yellow in breeding season
Common Raven
All black with a glossy purplish-blue iridescent sheen. Shaggy throat hackles, long wedge-shaped tail, and large robust build distinguish it from crows.
Large, powerful, curved black bill
About These Birds
Atlantic Puffin
The Atlantic puffin, often called the clown of the sea, is a charismatic seabird that nests in burrows on northern sea cliffs. Puffins can carry up to a dozen fish crosswise in their beaks at once thanks to backward-facing spines on their palate. Climate change and overfishing are threatening their food supply, leading to population declines.
