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.

King penguins primarily feed at the Antarctic Convergence, which provides 80% of their food biomass. [49] King penguins currently travel 300–500 km over the course of over a week to complete the journey. However, ocean warming could easily move these fronts further away from breeding grounds. Continuous ocean warming could cause the ...

[3] The males are larger than the females, and the weight of both drops while the parents raise their young.
The Galápagos penguin has a lifespan of 20 years, [5] but due to predation, life expectancy in the wild could be significantly reduced. They have been critically impacted to the point of endangerment by climate change and pollution caused by plastic waste due to tourism and urbanization .
