Emperor Penguin
Antarctic pack ice and surrounding Southern Ocean. The only penguin species that breeds during the Antarctic winter.
Song & Call Comparison

Highly varied: deep resonant 'kraa-kraa-kraa', hollow 'tok-tok', liquid 'klonk', and wing-whooshing. Among the most intelligent corvid callers; uses calls contextually in groups.
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.
Geographic Range & Migration
Common Raven
Holarctic distribution across North America, Europe, Asia, and North Africa. The most widely distributed corvid.
Emperor Penguin
Antarctic continent and surrounding sea ice. Breeding colonies are found along the entire Antarctic coastline.

About These Birds
Common Raven
The common raven is among the most intelligent birds, demonstrating tool use, future planning, and social manipulation in scientific studies. In many cultures, ravens feature prominently in mythology as creators, tricksters, or messengers. Their complex vocalizations include over 30 distinct calls.
Emperor Penguin
The emperor penguin is the tallest and heaviest of all penguin species. They breed in the harshest conditions on Earth, enduring Antarctic winter temperatures of -60 C and wind speeds of 200 km/h. Males incubate the single egg on their feet under a brood pouch for about 65 days while fasting.
