The Adélie penguin lives on sea ice but needs ice-free land to breed. With a reduction in sea ice, populations of the Adélie penguin have dropped by 65% over the past 25 years in the Antarctic Peninsula. [39] Young Adélie penguins that have no experience in social interaction may react to false cues when the penguins gather to breed.
Conservation status codes listed follow the International Union for Conservation of Nature (IUCN) Red List of Threatened Species. Range maps are provided wherever possible; if a range map is not available, a description of the penguin's range is provided. Ranges are based on the IOC World Bird List for that species unless otherwise noted ...
Sphenisciformes (from the Latin for "wedge-shaped") is the taxonomic order to which the penguins belong.

The emperor penguin is the heaviest and largest of the penguin species and is listed on the International Union for Conservation of Nature and Natural Resources’s Red List as near threatened.
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is an inventory of the global conservation status and extinction risk of biological species. [1]
The conservation status of a group of organisms (for instance, a species) indicates whether the group still exists and how likely the group is to become extinct in the near future. Many factors are taken into account when assessing conservation status: not simply the number of individuals remaining, but the overall increase or decrease in the ...
The Adélie penguin, or Pygoscelis adeliae, is a penguin species commonly found along the For flight-ready birds, these often involve complex dance moves and peacock-like displays of grandeur.
