The weight also varies by season, as both male and female penguins lose substantial mass while raising hatchlings and incubating their egg.

In 2009, German zookeepers gave an egg to a male same-sex pair of Humboldt penguins named Z and Vielpunkt, which hatched the egg and raised the chick.

Even though they live in large colonies, emperor penguins are the least common Antarctic penguins. Scientists estimate anywhere from 265,000 to 278,000 breeding pairs are left in the wild.
Most penguins lay two eggs in a clutch, although the two largest species, the emperor and the king penguins, lay only one. [62] With the exception of the emperor penguin, where the male does it all, all penguins share the incubation duties. [63] These incubation shifts can last days and even weeks as one member of the pair feeds at sea.
Emperor penguins hatch their eggs and raise their chicks on the ice that forms around the continent each Antarctic winter and melts in the summer months. Researchers used satellite imagery to look ...
