Size Comparison
Habitat Comparison
Common Myna
Urban areas, farmland, and open woodland. Closely associated with humans and one of the most successful avian urban colonizers.
Snowy Owl
Arctic tundra for breeding. Winters in open habitats resembling tundra, including prairies, airports, shorelines, and agricultural fields.
Song & Call Comparison
Common Myna
A noisy, cackling chatter and melodious whistling mixed together. An accomplished mimic of other birds and sounds. Gives repeated 'mee-ow' and harsh 'quarr' alarm 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

Native to South and Southeast Asia. Introduced and invasive in Australia, South Africa, Middle East, and many Pacific islands.
Snowy Owl
Circumpolar Arctic for breeding. Irruptive winter movements bring birds south to the northern United States, Europe, and Asia.

About These Birds
Common Myna
ハッカチョウ（Acridotheres tristis）— 南アジア原産で世界各地に移入された強い適応力をもつムクドリ科の鳥。黄色い嘴と目の周りの黄色い皮膚が特徴。
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.
