About These Birds
कॉकाटियल
The cockatiel is the smallest member of the cockatoo family and one of the most popular pet birds globally. These gentle, intelligent parrots can learn to whistle tunes and mimic sounds. Wild cockatiels are nomadic, traveling in flocks following food and water availability across the Australian outback.
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.
