Some of the zoos first animals were four King Penguins, a Gentoo Penguin and a Macaroni Penguin, who arrived in 1914, after a 7000 mile journey, the first penguins seen anywhere in the world outside of the South Atlantic, their home.

The Edinburgh Zoo, formerly the Scottish National Zoological Park, welcomed the first King Penguin hatchling in 1919, the first penguin hatched in a zoo anywhere in the world. It was a fairly new zoo at the time, opened to the public in 1913.

The first Macaroni Chick hatched at the Zoo in 1935. Macaroni penguins look a lot like Rockhoppers.
|Gentoo Penguins at feeding time|
In 1937, the first Gentoo chick made its appearance.

In 2013 it reopened after further improvements, and the penguins returned from their vacations in England, Ireland and Denmark. It is the largest Penguin pool in Europe, holding 1.2 million liters of water.

Edinburgh Zoo now hosts three kinds of penguins: King, Northern Rockhopper and Gentoo.

Since 1951, the penguins have participated in a daily parade. The legend is that the inaugural parade was an accident, after a keeper left a gate open and the penguins followed, to the delight of the zoo visitors.

Sometimes there are many penguins out strolling with the keepers, and some days it is only a few.
|The Penguin on the right has Leucism.|
A rare genetic mutation at the zoo some years ago resulted in a penguin with a beautiful muted silver tone of feathers. There are several of these leucistic Gentoo Penguins in Edinburgh.

Leucism occurs in the various species of Penguins in the wild, but they often don't live to adulthood, and are ostracized by the other penguins. In Edinburgh, however, the silver penguins are treated just the same by the other penguins. In fact the silvery penguin named Snowflake is a particular favorite among the other birds, and seems to always have a companion nearby, the keepers say.

The general consensus is that there are 17 distinct species of Penguins in the world, although several resemble each other, and there are some sub species. The smallest type is the Little (Blue) Penguin, which weighs a barely two pounds, and the largest is the Emperor Penguin, who stands four feet tall.

Some of them, such as the Emperor and King Penguins, live in the icy blasts of Antarctica, but other species make their homes on warmer shores, but all in the Southern Hemisphere.
The Penguins living in the Antarctic are being especially threatened by climate change, as their formerly stable breeding grounds on the ice shelf melt and fall into the sea.

While Penguins and Polar Bears are often housed near each other in zoos, and are often featured together on flannel pajamas and in TV commercials, they would never meet in the wild. Polar Bears live at the very Northern top of the world, and Penguins all live in the Southern Hemisphere, some very near the South Pole.
