Habitat Comparison
Emu
Open grasslands, savanna woodlands, scrublands, and semi-arid plains across Australia. Avoids dense forest and true desert.
Águia-rabalva
Coastlines, large lakes, and rivers with mature trees or cliffs for nesting. Requires large undisturbed areas.
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.
Águia-rabalva
High-pitched, yelping 'klee-klee' and deep barking 'ra-ra-ra'. Less vocal than Bald Eagle but similar chattering quality. Gives gull-like wailing near nest in breeding season.
Geographic Range & Migration

Throughout mainland Australia. Absent from Tasmania, where the Tasmanian emu was driven to extinction by 1850.

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.
Águia-rabalva
The white-tailed eagle is Europe's largest eagle and the fourth-largest eagle in the world. Once extinct in Britain, it has been successfully reintroduced to Scotland and Ireland through conservation programs. These powerful raptors can live over 25 years and form lifelong pair bonds.
