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-tailed Hawk
The red-tailed hawk is the most widespread and common hawk in North America. Its screaming cry is so iconic that it is often dubbed over bald eagle footage in films and television. These adaptable raptors thrive in human-altered landscapes and are a familiar sight perched along highways.
