Size Comparison
Habitat Comparison
European Robin
Woodlands, hedgerows, parks, and gardens across Europe. Remarkably tame around humans, especially in Britain.
Snowy Owl
Arctic tundra for breeding. Winters in open habitats resembling tundra, including prairies, airports, shorelines, and agricultural fields.
Song & Call Comparison
European Robin
Exquisite, melancholic melody of thin whistled phrases, rising and falling softly. Rich, warbling song year-round; both sexes sing. Alarm call is a sharp 'tic-tic-tic'.
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
European Robin
Europe, western Asia, and parts of North Africa. Northern populations migrate south in winter; western European populations are largely resident.
Snowy Owl
Circumpolar Arctic for breeding. Irruptive winter movements bring birds south to the northern United States, Europe, and Asia.

About These Birds
European Robin
The European robin is one of the most beloved birds in Britain, where it is the unofficial national bird. Despite its friendly demeanor toward humans, robins are fiercely territorial against their own kind, singing year-round to defend territory. Their distinctive song is one of the first to be heard at dawn.
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.
