They have several common names. In Australia, they are often referred to as Fairy Penguins because of their tiny size. In New Zealand, they are called Little Blue Penguins, or just Blue Penguins, owing to their indigo-blue plumage, and they are called Kororā in Māori.

Taxonomy

The Little Penguin was first described by German naturalist Johann Reinhold Forster in 1781. Johann Reinhold Forster ( October 22, 1729 &ndash December 9, 1798) was a German naturalist of partial Scottish There are several subspecies but a precise classification of these is still a matter of dispute. In Zoology, as in other branches of Biology, subspecies is the Taxonomic rank immediately subordinate to a Species. The White-flippered Penguin, is sometimes considered a subspecies, sometimes a distinct species, and sometimes a morph. The White-flippered Penguin ( Eudyptula albosignata albosignata) is a small Penguin about 30 cm tall and weighing 1 Polymorphism in biology occurs when two or more clearly different Phenotypes exist in the same population of a species — in other words the occurrence of more than one As the Australian and western South Island Little Penguins seem to be a distinct species[1] to which the specific name minor would apply, the White-flippered birds indeed belong to a distinct species, although not exactly as originally assumed. In zoological nomenclature a specific name or specific epithet is the second part (second name in the name of a Species (a Binomen)

Mitochondrial and nuclear DNA evidence suggests the split between Eudyptula and Spheniscus occurred around 25 million years ago, with the ancestors of the White-flippered and Little Penguins diverging about 2. In Cell biology, a mitochondrion (plural mitochondria) is a membrane-enclosed Organelle found in most eukaryotic cells. In Cell biology, the nucleus (pl nuclei; from Latin la ''nucleus'' or la ''nuculeus'' "little nut" or kernel is a membrane-enclosed 7 million years ago. [2]

Description

Little Penguin
Little Penguin

The Little Penguin typically grows to 43 cm (16 in) tall and weighs about one kilogram (2. Inches redirects here To see the Les Savy Fav album see Inches. 2 pounds). The male is a little larger than the female, although their plumage is similar. The head and upperparts are indigo in colour, with slate-grey ear coverts fading to white underneath, from the chin to the belly. The flippers are indigo above and white underneath. The dark grey-black bill is 3-4 cm long, the irises pale silvery- or bluish-grey or hazel, and the feet whitish above with black soles and webbing. An immature individual will have a shorter bill and paler upperparts. [3]

Like most seabirds, they have a long lifespan. The average for the species is 6. 5 years, but flipper ringing experiments have recorded individuals that have lived for over 20 years. Bird ringing (also known as bird Banding) is an aid to studying wild Birds by attaching a small individually numbered metal or plastic ring to their legs [4]

Little penguins have also been reported from Chile (where they are known as Pingüino pequeño or Pingüino azul) (Isla Chañaral 1996, Playa de Santo Domingo, San Antonio, 16 March 1997) but it is unclear whether these birds were vagrants.

Behaviour

Diet

These birds feed by hunting fish, squid, and other small sea animals, for which they travel and dive quite extensively. Fish are aquatic Vertebrate animals that are typically ectothermic (previously Cold-blooded) covered with scales, and equipped with two Squid are marine Cephalopods of the order Teuthida, which comprises around 300 species

Reproduction

Little Penguins live year-round in large colonies, with each individual breeding pair forming a burrow in which to raise their chicks (of which two are born at a time). Little Penguins typically return to their colonies to feed their chicks at dusk; the birds will tend to come ashore in small groups to provide some defense against predators which might pick off individuals one by one. In Australia, the strongest colonies are on cat-free and fox-free islands.

At Phillip Island, south-east of Melbourne, a viewing area has been set up to allow tourists to view the nightly "penguin parade". Phillip Island is located about 140km away from Melbourne Named after Governor Arthur Phillip, Phillip Island in Victoria Melbourne ( is the second most populous city in Australia, with a Metropolitan area population of approximately 3 Lights and concrete stands have been erected to allow visitors to see but not photograph the birds interacting in their colony, who are not bothered by their spectators. The "parade",which stands as a very popular attraction, brings half a million visitors a year. [5] Tourists to Perth in Western Australia can also make the short trip to Penguin Island to see the penguins and observe their normal behaviour. The Oamaru Blue Penguin Colony[6] is the New Zealand equivalent to Phillip Island's penguin parade.

Linus Torvalds, the original creator of Linux (a popular operating system kernel), was once bitten by a Little Penguin while on holiday in Australia. Linus Benedict Torvalds ( ˈtuːrvalds born December 28 1969 in Helsinki, Finland) is a Finnish software engineer Linux (commonly pronounced ˈlɪnəks In Computer science, the kernel is the central component of most computer Operating systems (OS Reportedly, this encounter encouraged Torvalds to select Tux as the official Linux mascot/logo.

In early March, 2007, 25 of the 37 penguins died from an unknown toxin following a change of gravel in their enclosure. [10][11][12] It is still not known what caused the deaths of the Little Penguins, and it was decided not to return the 12 surviving penguins to the same enclosure in which the penguins became ill. [13]

A new enclosure for the Little Penguin colony was opened at Sea World in 2008.

Predators

Little Penguins in the wild are sometimes preyed upon by New Zealand fur seals. A study done by researchers from the South Australian Research and Development Institute found that roughly 40 percent of seal droppings in South Australia's Granite Island area contained Little Penguin remains. Granite Island ( is a small island next to Victor Harbor, South Australia, not far from South Australia's Capital city Adelaide. [14]
