Size Comparison
Habitat Comparison
Harpyie
Tropical lowland rainforests, requiring large tracts of continuous forest with tall emergent trees for nesting.
Haussperling
Closely associated with human habitation. Found in cities, towns, farms, and any built environment. Rarely found far from people.
Song & Call Comparison
Harpyie
Rarely heard; emits mournful whistled screams 'wheee-oo' and low croaking grunts near the nest. Vocalizations poorly documented given its remote Amazonian habitat.
Haussperling
Monotonous series of chirping 'cheep' and 'chirrup' notes. Male gives 'chilp' song repeatedly. Flocks produce constant chirping chatter. No melodic song; purely functional calls.
Geographic Range & Migration
Harpyie
Central and South America from southern Mexico through Brazil and northern Argentina. Range is shrinking due to deforestation.
Haussperling
Native to Europe, Asia, and North Africa. Introduced to every continent except Antarctica, making it the most widely distributed wild bird.

About These Birds
Harpyie
Die Harpyie zählt zu den kraftvollsten Greifvögeln der Welt und besitzt Krallen von der Größe der Klauen eines Grizzlybären. Sie ist der Nationalvogel Panamas. Die größte Bedrohung für die Art ist die Abholzung der Wälder, da jedes Brutpaar ein weites Revier unberührten Waldes benötigt.
Haussperling
Der Haussperling ist vermutlich der weltweit erfolgreichste Vogel im Zusammenleben mit dem Menschen. 1851 in New York eingeführt, verbreitete er sich innerhalb weniger Jahrzehnte über ganz Nordamerika. Trotz seiner weltweiten Häufigkeit sind die Bestände des Haussperlings in Teilen Westeuropas deutlich zurückgegangen.
