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.
Laughing Kookaburra
The laughing kookaburra is the largest kingfisher in the world, famous for its raucous laughing call that has become an iconic sound of the Australian bush. Despite being a kingfisher, it rarely eats fish, preferring terrestrial prey. Family groups perform chorus calls at dawn and dusk to mark their territory.
