Specifics of their behavior were documented extensively by Apsley Cherry-Garrard (a survivor of [[Robert Falcon Scott]]’s fateful final journey to the [[South Pole]]) in his book The Worst Journey in the World. Cherry-Garrard noted: "They are extraordinarily like children, these little people of the Antarctic world, either like children or like old men, full of their own importance." Certain displays of their selfishness were commented upon by George Murray Levick, a Royal Navy surgeon-lieutenant and scientist who also accompanied Scott on his ill-fated British Antarctic Expedition of 1910, during his surveying of penguins in the Antarctic: | Specifics of their behavior were documented extensively by [[Apsley Cherry-Garrard]] (a survivor of [[Robert Falcon Scott]]’s fateful final journey to the [[South Pole]]) in his book The Worst Journey in the World.

The Adélie penguin is known to feed mainly on [[Antarctic krill]], ice krill, [[Antarctic silverfish]], sea krill, and [[glacial squid]] (diet varies depending on geographic location) during the chick-rearing season. The stable isotope record of fossil eggshell accumulated in colonies over the last 38,000 years reveals a sudden change from a fish-based diet to [[krill]] that started 200 years ago.

The stable isotope record of fossil eggshell accumulated in colonies over the last 38,000 years reveals a sudden change from a fish-based diet to [[krill]] that started 200 years ago. This is most likely due to the decline of the Antarctic fur seal since the late 18th century and baleen whales in the 20th century. The reduction of competition from these predators has resulted in a surplus of krill, which the penguins now exploit as an easier source of food. | ||
Jellyfish including species in the genera ''Chrysaora'' and ''Cyanea'' were found to be actively sought-out food items, while they previously had been thought to be only accidentally ingested. Similar preferences were found in the little penguin, yellow-eyed penguin, and Magellanic penguin. | Jellyfish including species in the genera ''Chrysaora'' and ''Cyanea'' were found to be actively sought-out food items, while they previously had been thought to be only accidentally ingested.

Adélie penguins are one of the most common types of penguins found in [[Westarctica]]'s borders. As such, it has become a common image utilized by the government hoping to capitalize on the Adélie's cuteness. | Adélie penguins are one of the most common types of penguins found in [[Westarctica]]'s borders.

On 20 November 2023, the [[Flag of Westarctica]] was carried to an Adélie penguin colony on [[D'Hainaut Island]] as part of the flag's journey to the [[Antarctic Peninsula]]. | |||
==Stamps== | |||
Three [[Stamps of Westarctica|stamps]] featuring Adélie penguins have been released by Westarctica as part of an animal series of stamps. The first two were released in 2005 and the third was released ten years later in 2015. All stamps were of the $1.60 denomination, which was the common price paid by the [[Grand Duke Travis|Grand Duke]] to ship individual title certificates in 2005. | Three [[Stamps of Westarctica|stamps]] featuring Adélie penguins have been released by Westarctica as part of an animal series of stamps.
