Mating habits

Some penguins mate for life, others for just one season. They generally raise a small brood, and the parents cooperate in caring for the clutch and for the young. During the cold season on the other hand the mates separate for several months to protect the egg. Usually, the male stays with the egg and keeps it warm, and the female goes out to sea and finds food so that when it comes home, the baby will have food to eat. Once the female comes back, they switch roles.

When mothers lose a chick, they sometimes attempt to "steal" another mother's chick, usually unsuccessfully as other females in the vicinity assist the defending mother in keeping her chick. As the young grow, they assemble in large groups called crèches in some species, such as Emperor Penguins.

Isabelline Penguins

Perhaps one in 50,000 penguins (of most species) are born with brown rather than black plumage. These are called Isabelline penguins, possibly in reference to the legend that the archduchess Isabella of Austria vowed not to change her undergarments until her husband united the northern and southern Low Countries by taking the city of Ostend--which took three years to accomplish. [1] Isabellinism is different from albinism, though the faded color of the plumage calls albinism to mind. Isabelline penguins tend to live shorter lives than normal specimens, since their backs aren't well camouflaged against the deep, and they are often passed over as mates, so the trait is selected against.

Name

Penguin is thought by some to derive from the Welsh words pen (head) and gwyn (white),[8] applied to the Great Auk, which had white spots in front of its eyes (although its head was black), or from an island off Newfoundland known as Pengwyn, due to a large white rock. (In the latter case, the name may also have come from Breton.) This theory is supported by the fact that penguins look remarkably like Great Auks in general shape.

It is also possible that penguin comes from the Latin pinguis, “fat”. This is supported by the fact that the corresponding words in most other languages (e.g., French pingouin, German Pinguin) have i instead of e as the first vowel.[8] However, a Welsh 'i' is often sound-shifted to an 'e' in the English language, so a Welsh origin cannot be dismissed.

Another theory states that the word is an alteration of “pen-wing”, with reference to the rudimentary wings of both Great Auks and penguins, but there is no evidence for this.

Penguins in popular culture

Penguins are popular around the world, primarily for their unusually upright, waddling pace and (compared to other birds) lack of fear of humans. Their striking black and white plumage is often likened to a tuxedo suit and generates humorous remarks about the bird being "well dressed". Perhaps in reaction to this cutesy stereotype, fictional penguins are occasionally presented as grouchy or even sinister. Penguins have also been the subject of many books and documentary films such as Happy Feet and Surf's Up, both CGI-Animated Animal Adventure Films, March of the Penguins, a documentary based on the migration process of Emperors, and a parody film entitled Farce of the Penguins. Mistakenly, some artists and writers have penguins based in the North Pole. This is incorrect as there are almost no wild penguins in the nothern hemisphere, and those only barely (northernmost of the Galápagos).
