Size Comparison
Habitat Comparison
Emperor Penguin
Antarctic pack ice and surrounding Southern Ocean. The only penguin species that breeds during the Antarctic winter.
Rock Pigeon
Originally cliff-nesting in Mediterranean regions. Now the quintessential urban bird, inhabiting cities worldwide on every continent.
Song & Call Comparison
Emperor Penguin
Loud, resonant trumpeting calls used for individual recognition in dense colonies. Each bird's call is unique in frequency. Also gives softer contact 'braying' notes.
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
Emperor Penguin
Antarctic continent and surrounding sea ice. Breeding colonies are found along the entire Antarctic coastline.
Rock Pigeon
Native to Europe, North Africa, and South Asia. Feral populations on every continent except Antarctica.

About These Birds
Emperor Penguin
体型最大、最重的企鹅。在南极冬季零下60摄氏度的环境中繁殖。雄鸟孵卵约65天，期间完全禁食。
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.
