Mating

I always thought that some breeds of penguins mated for life. That is not the case. According to the Smithsonian the Galapagos penguins have the highest reuniting rate of all penguins at 93 percent. As for the lowest reuniting rate of all penguins at 15 percent goes to the Emperor penguins. Here is an interesting tidbit: Penguins found in the Southern hemisphere are more likely to "divorce" their mate for newer ones due to the narrower window of breeding opportunities to be successful. I never thought a penguin could be so fickle.

Different Species

There are 18 species of penguins in the world. 13 of these penguins have declining population, and 5 of them are considered endangered.
 The names of the 18 species:
Adelie
African Penguin
Chinstrap Penguin
Emperor Penguin
Erect-Crested Penguin
Fiordland Penguin
Galapagos Penguin
Gentoo Penguin
Humboldt Penguin
King Penguin
Little Fairy Penguin
Macaroni Penguin
Magellanic Penguin
Northern Rockhopper Penguin
Royal Penguin
Snares Island Penguin
Southern Rockhopper Penguin
Yellow-Eyed Penguin

I wonder if these are trully the only penguins out there. I know explorers have not fully explored every inch of this world of ours. So how do we realy know if there are only 18 different kinds of penguins. I fully believe we have not discovered every kind of penguins out there, just like there are other species of different animals that have not been discovered. Some are being discovered every month.

Social Birds

Did you know that penguins are the most social of all birds? Well I can see that about them. They live in large groups so why would they not be socialable. I would think being around so many you would have to be. If you have ever been to an aquarium, most likely they will have an exhibit with penguins. Now, if you observe these penguins you will notice that they are social birds, for they are usually found with other penguins, unless they are swimming.
