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 ...
Southern rockhopper penguin: Eudyptes chrysocome: 2 460 000 [21] VU [21] [21] Only mature individuals were included in the count (1.23 million pairs); population has declined 34% in the past 37 years. [21] Magellanic penguin: Spheniscus magellanicus: 2 600 000 [22] LC [22] [22] Only mature individuals were included in the count (1.3 million ...
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 IUCN Red List of Threatened Species by the International Union for Conservation of Nature is the best known worldwide conservation status listing and ranking system. . Species are classified by the IUCN Red List into nine groups set through criteria such as rate of decline, population size, area of geographic distribution, and degree of population and distribution fragmenta
Gentoo penguins do not store as much fat as Adélie penguins, their closest relative; gentoos require less energy investment when hunting because the net gain of energy after hunting is greater in gentoos than Adélies. [26] As embryos, gentoos require a lot of energy to develop. Oxygen consumption is high for a developing gentoo embryo.
The emperor penguin is the largest species of penguin in the world and also one of the most unique. Instead of breeding in the warmer summer months like other penguin species, emperor penguins lay ...
Adélie Cove is a 186-ha tract of ice-free land on the coast of Terra Nova Bay in Victoria Land, Antarctica. It has been identified as an Important Bird Area by BirdLife International because it supports populations of seabirds , notably a breeding colony of about 11,000 pairs of Adélie penguins .
