The most afraid of cold birds penguins generally in a few months to lay eggs? Is it Antarctic May?

When we were kids, we all learned a text about baby penguins. So what month do penguins, the most cold-proof birds, lay their eggs? According to Dalian Aquarium commentator revealed that the southern hemisphere Gregorian calendar May-June, the northern hemisphere November-December is the penguin laying season. At this time, many people will have questions, May is winter in Antarctica, and penguins should not lay eggs in summer. In fact, male penguins hatching eggs is indeed a difficult task, because penguins breeding season is in the Antarctic winter weather, cold weather, snow and snow. Penguins reproductive period selected in the Antarctic winter, because the winter is less harmful, can improve the reproduction rate, at the same time, to the penguin to grow to independent activities and foraging, Antarctic summer will come, penguin can leave their parents, live their own life? This is also the result of penguins adapting to the Antarctic environment.

Penguins can be said to be the most cold-resistant birds. Emperor penguins, for example, are covered with feathers and have fat two to three centimeters thick under their skin. This special insulation equipment enables them to live freely in ice and snow at minus 60 degrees Celsius. If a human were exposed to such low temperatures, he would not survive more than ten minutes. In addition, penguins living in the cold zone have feathers in their nostrils to prevent snowflakes from entering their nostrils when it snows, while penguins in the temperate zone do not have such equipment.

Penguins are cold-hardy, but they are not heat-tolerant; penguins in temperate regions are mostly active at dawn or dusk, and in the middle of the day, they hide in the shade for summer! There is a Magellanic penguin in South America, which migrates to the beaches of Uruguay every July and August. When spring comes, if the water temperature and temperature rise suddenly, hundreds of penguins often die of heat!

Penguins belong to the penguin family of penguins, which is an ancient bird. They have lived on earth about 50 million years ago. There are now 18 penguin species in the world, distributed only in the southern hemisphere. With a few exceptions, most live on land and sea at or near Antarctica.

Penguins are super players among birds. Many waterfowl swim by paddling their webbed feet through the water. Penguin feet, though webbed, are used only as rudders for steering. The power to move forward depends entirely on their paddle-like wings, which flutter through the water.

There are 18 species of penguins living in the world. They are white-finned penguins, white-finned penguins, yellow-eyed penguins, magellanic penguins, Peruvian penguins, Galapagos penguins, emperor penguins, king penguins, adri penguins, Antarctic penguins, Gentoo penguins, Steelhorn penguins, horn penguins, snare horn penguins, macroni horn penguins and straight-crowned horn penguins.

Penguin evolution Archaeologists infer from penguin fossils that penguins lived in Australia, New Zealand and Antarctica between 140 million and 650 million years ago. According to experts, ancient penguins can fly (too god ~) penguins lived on land at that time, some ancient penguins as high as 2 meters, so probably no animals dare to touch penguins! Penguins have no natural enemies. Ancient penguins also had to go to the sea to find food, so large wings gradually evolved into flippers suitable for swimming.
