Penguins use their whole heads to stroke, in a motion referred to as "wiping". [14] Birds regularly fluff up their plumage and repeatedly shake their bodies while preening. Experiments have shown that the shaking action can "rezip" a majority of split feather barbules. [27] Birds cannot use their beaks to apply preen oil to their own heads.
Highly adapted for life in the ocean water, penguins have countershaded dark and white plumage and flippers for swimming. Most penguins feed on krill, fish, squid and other forms of sea life which they catch with their bills and swallow whole while swimming. A penguin has a spiny tongue and powerful jaws to grip slippery prey.
Some characteristics that differentiate them from the other penguins are their red eyes, orange beak, pink webbed feet, and the yellow and black spiky feathers they have on their head. [ 1 ] [ 3 ] Although their yellow and black spiky feathers differentiate them from other penguins, rockhopper penguin chicks do not have them; these feathers ...
Emperor penguins inhabit the compacted ice along the coast of Antarctica with some colonies established up to 11 miles inland. Unlike a number of other penguin species that may visit the continent ...
Snares penguins were originally collected in 1874 and named atrata by Frederick Hutton. However, Hutton lost his sample at sea whilst drawing the bird before a full speciation could be identified. A description written by Hutton and an illustration done by Keulemans in Buller's A History of the Birds of New Zealand are evidence that this is the ...
Penguins evolved their wing structure to become more efficient underwater at the cost of their efficiency in the air. [ 28 ] The only known species of flightless bird in which wings completely disappeared was the gigantic, herbivorous moa of New Zealand , hunted to extinction by humans by the 15th century.

King penguins mainly eat lanternfish, squid, and krill. On foraging trips, king penguins repeatedly dive to over 100 metres (300 ft), and have been recorded at depths greater than 300 metres (1,000 ft). [2] Predators of the king penguin include giant petrels, skuas, the snowy sheathbill, the leopard seal, and the orca.
