Size Comparison
Habitat Comparison
Common Starling
Open countryside, farmland, parks, and urban areas. Forms enormous communal roosts in winter, especially in urban environments.
Snowy Owl
Arctic tundra for breeding. Winters in open habitats resembling tundra, including prairies, airports, shorelines, and agricultural fields.
Song & Call Comparison
Common Starling
A complex mimic: rattles, whistles, clicks, and squeaks mixed with imitations of other birds. Song is a continuous medley. Also gives harsh 'scheer' alarm and chattering.
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 Starling
Native to Europe, western Asia, and North Africa. Introduced to North America, South Africa, Australia, and New Zealand.
Snowy Owl
Circumpolar Arctic for breeding. Irruptive winter movements bring birds south to the northern United States, Europe, and Asia.

About These Birds
Common Starling
紫翅椋鸟（Sturnus vulgaris）— 原产于欧亚大陆，已引入北美、澳大利亚和南非。具金属光泽的羽毛和白色斑点为特征。能形成壮观的大群（椋鸟旋舞）。
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.
