EGG-straordinary penguins and their eggs
The life of a penguin is not an easy one. Living outside in freezing -60 degrees weather and keeping an eye out for predators is as difficult as it sounds, and when you add needing to keep an egg at a sweltering 36 degrees through all of this... it sounds tough. But penguins are incredible creatures and egg-stremely tough! Let's look at a few species of penguins and how they look after their eggs.   EMPEROR PENGUINS Emperor penguins are the only species of penguin that lay just one egg, all other species lay two. The egg can measure about 11.1 to 12.7 cm long and weigh between 345 to 515g - that’s about the weight of 13 Cadbury’s Crème Eggs! What's more, this species is the only one that incubates the egg on its feet and it's the male that does this. Male Emperors have a special brood pouch – a flap of warm skin near their feet, in which they incubate the egg. Temperatures will get as low as -61 degrees Celsius, but the egg in the incubation pouch is a toasty 36 degrees. The male will take care of the egg for about 65-75 days until the female returns from feeding.   Emperor Penguins

  ADELIE PENGUINS Adelie penguins are the smallest penguin in the Antarctica and lay two eggs, each measuring 5.5 to 8.6 cm long and weighing between 61g to 153.5g. Male Adelies build nests to attract a female. Once the nest is built and he courts his lady love, the female will lay a clutch of two eggs that will be incubated by both adults for around 35 days.   Adelie Penguins

  GENTOO PENGUINS Gentoos, the Antarctic cousins of the Adelie penguin, also build nests. However, Gentoos make circular nests made of stones, grass, moss, and feathers. The female also lays two eggs, each within 3 days of the other, and both parents take turns incubating for more than a month before the chicks hatch.   Gentoo Penguins

  CHINSTRAP PENGUINS Chinstrap penguins are named this because of the thin chinstrap line under their beaks. This species also lays a clutch of two eggs and make their nests from stones. Their eggs measure 7cm long and 5.5cm wide and weigh up to 120g. Both parents take it in turns to incubate the eggs and they hatch after about a month.   Chinstrap Penguins

    Penguins might be tough birds, but they face bigger challenges than raising their young:
  • Melting sea ice and overfishing reduces the amount of krill (their main food source) in the ocean.
  • Rising temperatures reduce the amount of sea ice penguins live on and can lead to penguin chicks hatching at times when food is more scarce.
  • The increase of floating ocean plastic can be ingested by penguins.
