Size Comparison
Habitat Comparison
Atlantic Puffin
Breeds on grassy cliff tops and offshore islands. Spends winter entirely at sea in the North Atlantic.
Snowy Owl
Arctic tundra for breeding. Winters in open habitats resembling tundra, including prairies, airports, shorelines, and agricultural fields.
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.
Snowy Owl
Male gives a deep booming hoot 'hooooo' and a rising 'hoo-hoo' series. Also barks sharply when alarmed. Quieter than many owls; silent during long Arctic winter hunts.
Geographic Range & Migration
Atlantic Puffin
North Atlantic from eastern Canada and northeastern United States to Iceland, Norway, and northwest Russia.
Snowy Owl
Circumpolar Arctic for breeding. Irruptive winter movements bring birds south to the northern United States, Europe, and Asia.

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
Snowy Owl
Adult males are almost entirely white. Females and immatures have dark brown barring and spotting. Yellow eyes and fully feathered feet.
Dark hooked bill mostly hidden by dense facial feathering
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.
Snowy Owl
The snowy owl is the heaviest North American owl and one of the most charismatic Arctic birds. Unlike most owls, it is largely diurnal, necessitated by the continuous daylight of Arctic summers. Snowy owl irruptions — periodic mass southward movements — are tied to lemming population cycles.
