I promised you something different in the avian line.
It IS a bird! It does not fly! It is NOT the emu.
It is a small bird but not a budgerigar—we discussed these already.

Quote:Little penguin
The little penguin (Eudyptula minor) is the smallest species of penguin in the world, and originates from New Zealand. It is commonly known as the fairy penguin, little blue penguin, or blue penguin, owing to its slate-blue plumage and is also known by its Māori name kororā. It is a marine neritic species that dives for food throughout the day and returns to burrows on the shore at dusk. Eudyptula minor feathers are dense in melanosomes, which increase water resistance and give them their unique blue colour.[3]
The Australian little penguin (Eudyptula novaehollandiae), from Australia and the Otago region of New Zealand, was initially described as Spheniscus novaehollandiae in 1826[4] and was later classified as Eudyptula minor novaehollandiae, a subspecies of the little penguin.[4][5]
Taxonomy

The little penguin was first described by German naturalist Johann Reinhold Forster in 1781. Several subspecies are known, but a precise classification of these is still a matter of dispute. The holotypes of the subspecies E. m. variabilis[6] and Eudyptula minor chathamensis[7] are in the collection of the Museum of New Zealand Te Papa Tongarewa. The white-flippered penguin (E. m. albosignata or E. m. minor morpha albosignata) is currently considered by most taxonomists to be a colour morph or subspecies of Eudyptula minor. In 2008, Shirihai treated the little penguin and white-flippered penguin as allospecies.[8] However, as of 2012, the IUCN and BirdLife International consider the white-flippered penguin to be a subspecies or morph of the little penguin.
Little penguins from New Zealand and Australia were once considered to be the same species, called Eudyptula minor. Analysis of mtDNA in 2002 revealed two clades in Eudyptula: one containing little penguins of New Zealand's North Island, Cook Strait and Chatham Island, as well as the white-flippered penguin, and a second containing little penguins of Australia and the Otago region of New Zealand.[9] Preliminary analysis of braying calls and cluster analysis of morphometrics partially supported these results.[9] A 2016 study described the Australian little penguin as a new and separate species, Eudyptula novaehollandiae. E. minor is endemic to New Zealand, while E. novaehollandiae is found in Australia and Otago.[5] A 2019 study supported the recognition of E. minor and E. novaehollandiae as separate species.[10]
The IUCN assessment for Eudyptula minor uses Eudyptula minor and Eudyptula novaehollandiae interchangeably throughout the report to specify location, but considers them as two genetically distinct clades within the same species.[1]
Description

Like those of all penguins, the wings of Eudyptula species have developed into flippers used for swimming.
Eudyptula species typically grow to between 30 and 33 cm (12 and 13 in) tall and on average weigh 1.5 kg (3.3 lb). The head and upper parts are blue in colour, with slate-grey ear coverts fading to white underneath, from the chin to the belly. Their flippers are blue in colour. The dark grey-black beak is 3–4 cm long, the irises pale silvery- or bluish-grey or hazel, and the feet pink above with black soles and webbing. An immature individual will have a shorter bill and lighter upperparts.[11]
Like most seabirds, the Eudyptula species have a long lifespan. The average for the species is 6.5 years, but flipper ringing experiments show that in very exceptional cases they may live up to 25 years in captivity.[12]
Eudyptula minor does not have the distinct bright blue feathers that distinguish Eudyptula novaehollandiae. In addition, the vocalisation patterns of the New Zealand lineage located on Tiritiri Matangi Island vary from the Australian lineage located in Oamaru. Females are known to prefer the local call of the New Zealand lineage.
There are also behavioural differences that help differentiate these penguins. Those of the Australian lineage will swim together in a large group after dusk and walk along the shore to reach their nesting sites. This may be an effective predator avoidance strategy by traveling in a large group simultaneously. This has not been seen by those of the New Zealand lineage. Eudyptula minor only recently encountered terrestrial vertebrate predators, while Eudyptula novaehollandiae would have had to deal with carnivorous marsupials.
