Habitat Comparison
Common Ostrich
Open arid and semi-arid habitats including savannas, Sahel, and dry woodlands across Africa.
Hawfinch
Deciduous and mixed woodland, orchards, parks, and large gardens with mature fruiting trees.
Song & Call Comparison
Common Ostrich
Male produces a surprisingly deep, resonant booming roar — remarkably lion-like. Also gives whistling and hissing sounds. Females and chicks emit softer grunts and squeaks.
Hawfinch
A sharp, metallic 'tsick' call — the primary vocalization and often all that's heard. Song is a thin, reedy warble. Generally inconspicuous vocally despite its striking appearance.
Geographic Range & Migration
Common Ostrich
Sub-Saharan Africa. Formerly also found in the Middle East and parts of Asia. Farmed worldwide.

About These Birds
Common Ostrich
The common ostrich is the world's largest living bird, standing up to 2.7 meters tall and weighing up to 145 kg. Despite being flightless, it is the fastest bird on land, sprinting at speeds up to 70 km/h. Ostrich eggs are the largest of any living bird, weighing about 1.4 kg each.
Hawfinch
The hawfinch possesses the most powerful bill relative to body size of any European bird, capable of cracking cherry stones that require a force of 27-43 kg. Despite its distinctive appearance, it is famously shy and difficult to observe. The skull contains special adaptations to absorb the enormous forces generated during seed-cracking.
