About These Birds
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.
Red-crowned Crane
The red-crowned crane is one of the rarest crane species and a potent symbol of longevity and fidelity in East Asian culture. Their elaborate unison call and dancing displays have inspired art and folklore for millennia. The resident population on Hokkaido, Japan, recovered from about 33 birds in 1952 to over 1,800 today.
