What makes the breeding of Emperor Penguins so unusual?
Of all penguin species, the Emperor Penguin (Aptenodytes forsteri) breeds in the coldest environment.
Emperor Penguins breed in regions with air temperature that descends to minus-40 degrees Fahrenheit (-40 C) and has winds that blow up to 89 mph (144 km/hr).
Additionally, the Emperor Penguin has the longest incubation period of any penguin averaging about 65 days.
Emperor Penguins also have the widest range of vocalizations of any penguin due largely to their breeding habitat of not having any fixed nesting ground, but relying, instead, on being able to recognize the vocal sounds of family members to stay together.
Lastly, the Emperor Penguin is the only penguin to breed during the Antarctic winter. All other penguins species breed in the spring and summer months.
