About These Birds
Eastern Bluebird
The eastern bluebird is a beloved symbol of happiness in North America. Once declining due to habitat loss and competition from introduced species, populations recovered dramatically thanks to a massive citizen science nest box campaign. These gentle thrushes form loose winter flocks and huddle together in nest boxes during cold snaps.
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.
