Chapter 15 flightless bird

Dear Xiaowen: Although chickens and ducks do not fly, they can sometimes spread their wings and fly for a short distance, which means that they are also called birds.But there are several "birds" in the world that don't even know the meaning, that is, ostrich (ostrich, the largest bird in the world), emu (emu), penguin (penguin), and ostrich (kiwi), their Some features, Dad made a watch for you: ostrich emu penguin kiwi fly no no no i won't run very fast, run forty miles an hour run thirty miles an hour slow death slow death Size three hundred pounds to one thousand pounds one hundred pounds fifteen to one hundred pounds as big as a chicken

The largest production area is Madagascar (the fourth largest island in the world). Australia has the most in Antarctica and New Zealand has the most. The hatchling of the egg white mother, At night, the male brooding female's tube-born don't care about brooding, The male has to incubate the mother's tube and don't care about hatching. The male had to hatch (Do not eat, hatch for two months) The mother said "Anyway, I don't hatch, I want to hatch you", So the male had to hatch (seventy-five days) Those who have their own merits can ask for a concubine.It is said that when you are chased to nowhere, you can put your head in the sand, as long as you can't see the enemy, you can rest assured, regardless of whether the enemy can see it or not.This kind of self-deception that refuses to face it is called ostrich like in English (in fact, this legend is wrong. When cornered, it will kick people, and will not hide its head and show its tail.) It can swim, swims very well, and eats fish.Not afraid of the cold, hatching a little penguin is like hatching a fur coat.The winter in Antarctica is as cold as minus 40 degrees to below 80 degrees, but the body temperature of male penguins hatching chicks is higher than that of humans.Penguins can’t recognize men and women clearly. If a male penguin thinks that a certain penguin seems to be a female, he will find a small stone and throw it in front of the other penguin. If the other penguin is a female, he will accept the small stone as a gift; It has the right to lose its temper for this misunderstanding, and it has the right to bite it. It must be willing to be bitten and not fight back.The nostrils are at the front of the beak, while those of other birds are at the back of the beak.The ground crew (non-flying) in the Air Force are called kiwi sarcastically.

Other flightless birds include cassowary in Australia and rhea in South America. dad January 6, 1974 P.S. Your letter on the 20th was received on the 5th.I want to write to a friend to buy a book, and I will write to grandma next time.
