Size Comparison
Habitat Comparison
Emu
Open grasslands, savanna woodlands, scrublands, and semi-arid plains across Australia. Avoids dense forest and true desert.
European Roller
Warm, dry, open country with scattered trees and nest holes. Breeds in tree cavities, earth banks, and nest boxes.
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.
European Roller
A harsh, grating 'rack-rack' or 'quarrk' in flight. Gives a variety of sharp nasal calls at the nest. Not melodic; primary vocalizations are alarm and contact calls.
Geographic Range & Migration
Emu
Throughout mainland Australia. Absent from Tasmania, where the Tasmanian emu was driven to extinction by 1850.
European Roller
Southern and eastern Europe, Central Asia, and North Africa. Winters in sub-Saharan Africa.

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.
European Roller
The European roller gets its name from the spectacular rolling and tumbling aerial displays performed by males during courtship. It is the only roller species in Europe and one of the continent's most colorful birds. Declining across much of its western range due to agricultural intensification and habitat loss.
