All the world’s 18 penguin species live in the Southern Hemisphere, with two that live and breed in the Australian Antarctic Territory (AAT): the medium-sized Adélie Penguin (Pygoscelis adeliae) and the largest and tallest of all penguin species, the Emperor Penguin (Aptenodytes forsteri).

Both Adélie and Emperor Penguins can swim several hundreds of kilometres from their colonies in search of food. Like all penguin species, penguins of the AAT catch their prey by pursuit-diving, using their flippers to “fly” through the water.

This stamp issue presents striking close-up and group photographs of each species.

Stamps in this issue

$1.10 Emperor Penguin

The largest and tallest of all penguin species, the Emperor Penguin can weigh up to 40 kilograms. They are adapted to the extreme cold and wind, with several layers of feathers, large reserves of fat and small beaks and flippers to minimise heat loss. Up to several hundred birds huddle together for warmth, taking turns to occupy the warmest and coldest positions.

$1.10 Emperor Penguins with chicks

Emperor Penguins typically breed on fast-ice near the coastline and are the only penguins to breed in the Antarctic winter. One egg is laid in May or early June. The female gently transfers it to the feet of the male before heading out to sea to fish, leaving the father to incubate the egg, without eating, for around 65 days.

$2.20 Adélie Penguin

The Adélie Penguin weighs from three to six kilograms and measures around 70 centimetres from the tip of the beak to the tip of the tail, has a white ring surrounding the eye.

$2.20 Group of Adélie Penguins

Adélie Penguins breed annually between October and February at ice-free sites around the coastline, including near Mawson station in the AAT. Two eggs are laid in a nest made of pebbles and are incubated in turn by both parents.
