Habitat Comparison
Common Blackbird
Woodland, hedgerows, gardens, and parks. One of the most common garden birds across Europe.
Snowy Owl
Arctic tundra for breeding. Winters in open habitats resembling tundra, including prairies, airports, shorelines, and agricultural fields.
Song & Call Comparison
Common Blackbird
Arguably Britain's finest songster: rich, flute-like phrases with deep, mellow quality. Sings persistently at dusk. Alarm is a sharp 'chook-chook'. Song includes liquid 'pew' notes.
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
Common Blackbird
Europe, Asia, and North Africa. Introduced to Australia and New Zealand. Northern populations are migratory.
Snowy Owl
Circumpolar Arctic for breeding. Irruptive winter movements bring birds south to the northern United States, Europe, and Asia.

About These Birds
Common Blackbird
クロウタドリ（Turdus merula）— ヨーロッパに広く分布するツグミ科の鳥。オスは全身黒く黄色い嘴をもち、メスは茶色。庭園や森林に生息し、美しい歌声をもつ。
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.
