The life-cycle of the emperor penguin. The penguins start courtship in March or April, when the temperature can be as low as −40 °C (−40 °F). A lone male gives an ecstatic display, where it stands still and places its head on its chest before inhaling and giving a courtship call for 1–2 seconds; it then moves around the colony and ...
Penguins are a group of aquatic flightless birds from the family Spheniscidae (/ s f ɪ ˈ n ɪ s ɪ d iː,-d aɪ /) of the order Sphenisciformes (/ s f ɪ ˈ n ɪ s ə f ɔːr m iː z /). [4] They live almost exclusively in the Southern Hemisphere: only one species, the Galápagos penguin, is found north of the Equator.
The penguins start courtship in March or April, when the temperature can be as low as –40°C (–40°F). In May or June, the female penguin lays one 450 g (1 lb) egg , but at this point her nutritional reserves are exhausted and she must immediately return to the sea to feed.
Magellanic penguin on Argentina's coast Skeleton of a Magellanic penguin. Magellanic penguins are medium-sized penguins which grow to be 61–76 cm (24–30 in) tall and weigh between 2.7 and 6.5 kg (6.0 and 14.3 lb).

The king penguin has an extremely prolonged breeding cycle, taking around 14–16 months from laying to offspring fledging. [42] Although pairs will attempt to breed annually, they are generally only successful one year in two, or two years in three in a triennial pattern in South Georgia. [ 35 ]
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.
Despite having first been recorded by Captain Cook in the late 1790s, the first emperor penguin colony wasn’t discovered until 1902. Because they dwell in such extreme southern climes that are ...
