Habitat Comparison
Belted Kingfisher
Rivers, streams, lakes, ponds, estuaries, and coastlines with clear water and suitable perches. Nests in burrows dug into earthen banks.
Emu
Open grasslands, savanna woodlands, scrublands, and semi-arid plains across Australia. Avoids dense forest and true desert.
Song & Call Comparison
Belted Kingfisher
A loud, rattling 'klee-klee-klee-klee' — mechanical and penetrating. Given in flight along rivers. Also a harsh 'kekekek' near nest. Far louder than Common Kingfisher.
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.
Geographic Range & Migration
Belted Kingfisher
North America from Alaska and Canada to Central America and the Caribbean. Northern populations migrate south in winter.
Emu
Throughout mainland Australia. Absent from Tasmania, where the Tasmanian emu was driven to extinction by 1850.

About These Birds
Belted Kingfisher
The belted kingfisher is unusual in that the female is more colorful than the male, sporting an additional rufous belly band. These noisy birds announce their territory with a distinctive rattling call. They excavate nesting burrows up to 2.4 meters deep into riverbanks using their heavy bills.
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.
