Size Comparison
Habitat Comparison
Hawfinch
Deciduous and mixed woodland, orchards, parks, and large gardens with mature fruiting trees.
Rock Pigeon
Originally cliff-nesting in Mediterranean regions. Now the quintessential urban bird, inhabiting cities worldwide on every continent.
Song & Call Comparison
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.
Rock Pigeon
Soft, rhythmic cooing 'roo-c'too-coo' repeated multiple times, with emphasis on second syllable. Male courtship coo is deeper and more persistent. Wing-clapping on takeoff is loud.
Geographic Range & Migration
Hawfinch
Europe, North Africa, and western and central Asia. Partially migratory, with northern populations moving south in winter.
Rock Pigeon
Native to Europe, North Africa, and South Asia. Feral populations on every continent except Antarctica.

How to Tell Them Apart
Hawfinch
Orange-brown head with a black bib and eye stripe. Warm brown back, grey nape, and broad white wing bar. Massive head and bill give a top-heavy appearance.
Enormously powerful, conical, pale bill capable of cracking cherry and olive stones
Rock Pigeon
Wild-type has a blue-grey body with iridescent green and purple neck feathers, two black wing bars, and a white rump. Feral populations show enormous color variation.
Slender dark bill with a white fleshy cere at the base
About These Birds
Hawfinch
シメはヨーロッパの鳥の中で体の大きさに対して最も強力なくちばしを持ち、27〜43 kgの力でサクランボの種を割ることができる。その特徴的な外見にもかかわらず、著名なほど恥ずかしがり屋で観察が難しい。種割り時に発生する巨大な力を吸収するための頭骨の特殊な適応を持つ。
Rock Pigeon
The rock pigeon is the ancestor of all domestic pigeon breeds and one of the most abundant birds in cities worldwide. Pigeons have served humans as messengers, food, and subjects for scientific research — their homing ability and vision have been studied extensively. Darwin's study of pigeon breeding contributed to his theory of evolution.
