The men are larger and heavier than females.Adults face fins jugular "are black with white border, the inner faces of the fins are white.

Penguins are considered the most aggressive species of penguin The predator jugular adult Leopard Seal. Eggs and chicks can fall victim to birds such as skuas and sheath bills brown. On land, build nests circular stones, and lay two eggs, which are incubated by the male and female quarters for 6 days. The chicks hatch after about 37 days, and the soft gray backs and white fronts. Penguins, by its nature, the eggs hatch and are social creatures.

Crested Penguin

 

The Life of Animals | Crested Penguin | Crested penguins are similar in appearance, have clearly defined black and white plumage with red beak and prominent yellow crest. The real penguin (especially) has a white face, while other species have black faces. Crested penguins lay two eggs, but usually only raise a young and successful. All species have the curious phenomenon of egg size dimorphism in breeding, the first egg (or egg), which is substantially lower than the second egg (B-egg). British ornithologist David Lack gender theory evolved into the construction of a single egg clutch.

Recently penguin breeding and peak drawn was reported that eggs smaller than the second peak is expected. DNA evidence suggests that mitochondrial and nuclear crested penguins ancestors split from its closest relative, the yellow-eyed penguin middle Miocene about 15 million years before splitting into separate species about 8,000,000 years ago, at the end of the Miocene. Type fossil penguin Madrynornis was identified as the closest known relative of rockhopper penguins.

Six extant species have been traditionally recognized, with the recent division of Penguin Rockhopper bringing in September, however, the close relationship of macaroni and penguins, and erect-crested penguins and Snares have led some to propose that the two pairs must be considered as a species.

African Penguin

  

The Life of Animals | African Penguin | African penguins grow 68-70 cm (26.7 to 27.5 in) tall and weigh between 2 and 5 kg (4.4 and 11 lbs), you have a single black stripe and black spots on the chest, pattern of dots for each penguin, like human fingerprints. The African Penguin is on the southwest coast of Africa, living in colonies on 24 islands between Namibia and Algoa Bay, near Port Elizabeth, South Africa. It 'the only penguin species that breeds in Africa and his presence gave the name of the islands Penguin. Mainland colonies probably only recently due to the reduction in the number of possible predators, although Betty's Bay colony has been attacked by leopards.

Boulders Beach is a tourist attraction for swimming beach, and penguins. African penguins feed on the open sea, where they pursue pelagic fish such as sardines and anchovies (Engraulis capensis for example) and marine invertebrates such as squid and small crustaceans consume a penguin up to 540 grams of prey can every day, but this increases above 1 kg when lifting the African penguin chicks elderly is monogamous. Chicks fledge at 60 to 130 days. When penguins outline, are not able to feed their new feathers are not waterproof yet, so that rapidly throughout the moult, which lasts about 20 days of African penguins

The average lifespan of an African penguin is 10 to 27 years in the wilderness, and perhaps longer in captivity. However, the African penguin can often fall thieves. Their predators are sharks in the sea, Cape seals and occasionally killer whales. Land-based enemies include mongoose, Genets, domestic cats, and the Kelp Gull stealing their eggs and newly hatched chicks The African Penguin is a species of which the Agreement on the Conservation of African-Eurasian migratory waterfowl (AEWA) applies. The African penguin in the Red Book of the data listed as a species in danger of extinction.

In September 2010, the African penguin was listed as endangered under the laws of the United States Endangered Species. 5,000 breeding pairs estimated to live in Namibia in 2008, in 2009, about 21,000 pairs were estimated to live in South Africa

Adelie Penguins

The Life of Animals | Adelie Penguins | There are 38 colonies of Adelie penguins, and more than 5 million Adélie in the Ross Sea region. Ross Island supports a colony of about half a million Adelie penguins. Adelie penguins breed from October to February, on the coast around the Antarctic continent. Adelie nests built of rough stones. Adelie penguins live in groups called colonies. These penguins are medium in size and weight of 46-75 cm (18-30 inches) long and 3.6 to 6 kg (7.9 to 13 pounds). The tail is a "little more than penguins queues. I am a bit "lower than other penguin species. His appearance is closer to the stereotypical image of penguins, like most black with a white belly. Adelie penguins can swim up to 45 mph (72 km / h) Adelie penguins are leopard seals prey, Skua and whales occasionally fatal.

Like all penguins, the Adelie highly social, feeding and nesting of groups. They are also very aggressive to other penguins who steal stones from their nest. Cherry-Garrard, said: "They are extraordinarily like children, of these people around the world, Antarctica, either as children or old men, full of self-importance. E 'was observed as the Penguin intrigue could put them in danger, Scott found a particularly troublesome The big problem with dog teams is due to the reckless behavior of penguins. These groups were jumping constantly in our iceberg. Since landing on your feet the whole attitude expressed devouring curiosity and a head of pork contempt for his own safety.

to the South Pole has been more receptive to this element of intrigue to Adelia Cherry-Garrard Meares and Dimitri-exercised dogs dog teams on the counter over, when we were stopped for a period of time. For stubborn personality characteristics Cherry-Garrard kept the bird in high esteemThe restriction of competition from these predators led to a surplus of krill, the penguins now used as a source of penguins fooddélie easier to reach their breeding grounds in October or November, in late winter and early spring. Nests consist of stones stacked.

In December, the warmest month in Antarctica (about -2 ° C or 28 ° F), parents take turns incubating the eggs, you'll eat and the other stays to warm the egg. The parent who is incubating does not eat. In March, young adults and their return to the sea. The Adelie penguin living on sea ice, but needs the ice-free land to breed. With the reduction of sea ice and food shortages, the population of Adelie penguins fell 65% in the last 25 years. Adelie penguins youth who have no experience in social interaction can respond to fake stimuli as penguins gather to breed.  Due to the emergence of birds and relatively similar to human behavior, human observers have interpreted this behavior as sexual deviation anthropomorphic.

The brochure, declined for publication in the official reports of the Scott expedition, said the frequency of sexual activity, an auto-erotic behavior, and the apparently anomalous behavior of men and women, young couples, including necrophilia, sexual coercion, sexual abuse and physical chicks and homosexual behavior, "says an analysis by William Russell and his colleagues Douglas Sladen and David Ainley. Levick observe Adelie penguins at Cape Adare, the site of the largest colony of Adelie penguins in the world. The discovery significantly clarifies the behavior of the species that some researchers believe it is an indicator of climate change Adelie penguins live in the area of the Ross Sea, Antarctica and the migration of an average of about 13,000 kilometers (8,100 miles) during the year that follows the sun from their breeding colonies of winter feeding areas and vice versa versa. Longer trips were recorded at 17,600 km (10,900 miles)
