Size Comparison
Habitat Comparison
Belted Kingfisher
Rivers, streams, lakes, ponds, estuaries, and coastlines with clear water and suitable perches. Nests in burrows dug into earthen banks.
House Sparrow
Closely associated with human habitation. Found in cities, towns, farms, and any built environment. Rarely found far from people.
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.
House Sparrow
Monotonous series of chirping 'cheep' and 'chirrup' notes. Male gives 'chilp' song repeatedly. Flocks produce constant chirping chatter. No melodic song; purely functional calls.

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.
House Sparrow
The house sparrow is perhaps the most successful bird in the world at living alongside humans. Introduced to New York in 1851, it spread across North America within decades. Despite its global abundance, house sparrow populations have declined significantly in parts of western Europe.
