How to penguins reproduce?

Pretty much in the same way that all other birds reproduce - the female is mounted by the male and sperm passed from cloaca to cloaca. The egg is fertilized at ovulation, but yolk development starts 14-17 days before this. After that the alumen (white) and shell are added and the egg moves down the oviduct. In all it takes around 23 days. The second egg is laid after 3-4 days.





What do penguins drink ?

Penguins drink any water they can get access to - fresh or salt. When ashore they will drink fresh water from pools and streams and can sometimes be seen drinking water preened off their backs during rain showers. At sea penguins must drink salt water and they are able to do this because they have special glands abound the eye sockets that extract excess salt from the blood. The excess salt is excreted as a salty fluid through the nasal passages.
