Size Comparison
Habitat Comparison
Emu
Open grasslands, savanna woodlands, scrublands, and semi-arid plains across Australia. Avoids dense forest and true desert.
Snowy Owl
Arctic tundra for breeding. Winters in open habitats resembling tundra, including prairies, airports, shorelines, and agricultural fields.
Song & Call Comparison
Emu
Deep, resonant booming grunt 'e-moo', often repeated 3 times. Females give a deep drumming call produced by an inflatable throat pouch. Generally low-pitched and far-carrying.
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
Emu
Throughout mainland Australia. Absent from Tasmania, where the Tasmanian emu was driven to extinction by 1850.
Snowy Owl
Circumpolar Arctic for breeding. Irruptive winter movements bring birds south to the northern United States, Europe, and Asia.

Dark hooked bill mostly hidden by dense facial feathering
About These Birds
Emu
The emu is the second-tallest living bird and the largest bird native to Australia. It is the only bird with calf muscles, enabling powerful running at up to 50 km/h. In the famous Emu War of 1932, the Australian military was deployed against crop-raiding emus — and the emus arguably won.
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.
