Recently, the fifth grade Ke Zishuo children can be described as not sounding, a blockbuster. He is usually very interested in the field of natural sciences and attaches great importance to the accumulation of scientific knowledge.
Recently inadvertently found that a famous mineral water packaging on the pine sparrow eagle pattern appeared a printing error, and this error is only found through a feather, I believe that "popular science brother" Zhang Chenliang saw this report, will also feel that this "small museum monarch" is really the Yangtze River after the wave pushing the front wave.
Scientists have always believed that science popularization work should start from dolls, cultivate their interest from an early age, and believe that knowledge is power and knowledge is a weapon.
During the period of the War to Resist US Aggression and Aid Korea, the United States once dropped tens of thousands of virus-contaminated spiders in North Korea, but ordinary people simply could not distinguish what was different from these spiders, at that time many domestic biologists volunteered to go to the battlefield to complete the task of identifying spiders, and finally determined that the United States had airdropped virus spiders, and scientists in the field of natural sciences contributed their share of light and heat.
Over the years, because scientists have worked tirelessly to popularize science, many children have also been very interested in science, and Ke Zishuo children are one of them. We often drink mineral water, but who will notice its packaging? Ke Zishuo did it.
Ke Zishuo, a child in the sixth grade of the fifth grade of Wenyi Street Primary School in Hangzhou, found that the packaging of some kind of mineral water was printed with an eagle flying with its wings spread, and the following was marked as a pine sparrow eagle. Through careful observation, he found that there was a slight difference between the printed sparrowhawk and the real sparrowhawk.
The printed sparrowhawk has 6 wing fingers, while the real sparrowhawk has only five, and their heads are slightly different, so Ke Zishuo wrote an essay to express his point of view.
Last night, the misprinted mineral water company also responded to the matter on the Internet, praised Ke Zishuo, and in order to encourage his spirit of serious study, he gave a library card worth 10,000 yuan to the school he attended.
However, birds of prey like the pine sparrowhawk are really rarely noticed, so it is also very important to popularize the science of birds of prey. The pine sparrowhawk printed on the mineral water packaging is actually a member of the order Hawks, birds of prey, divided into hawks, falcons and owls.
The eagle order is the largest order of birds of prey, in addition to what we usually call the eagle, but also includes many family members, eagle members are increasingly prosperous, but we know very little about it, for this mysterious and cold creature, it is really necessary to talk about it.
There are actually two types of pine sparrowhawks, the pine sparrowhawk and the Japanese pine sparrowhawk. They are direct relatives, they are even more intimate than the eagle brother Harrier brother, at first glance it is like a pair of twins, their wing fingers are 5, and the external outline is very similar.
For a long time, the Japanese pine sparrowhawk was considered a subspecies of the pine sparrowhawk, but after 1990, the DNA analysis comparison technology matured to determine that the pine sparrowhawk and the Japanese pine sparrowhawk were two different separate species.
So how do you distinguish between the Japanese Sparrowhawk and the Sparrowhawk? The Japanese pine sparrowhawk, which mainly breeds in Northeast Asia, is a migratory bird, and when the cold winter comes, it will travel to the south of China and Southeast Asian countries such as Thailand and Myanmar to spend the winter.
The pine sparrowhawk is a typical resident bird, they are distributed in the south of China and Southeast Asian countries, whether it is the pine sparrowhawk and the Japanese pine sparrowhawk they are very afraid of cold birds.
The Japanese pine sparrowhawk is relatively delicate, the throat line is very thin, while the throat line of the pine sparrowhawk is very obvious, and the pine sparrowhawk has a very rough pattern on the chest, and the Japanese pine sparrowhawk is more delicate.
The middle finger of the Japanese pine sparrowhawk and the pine sparrowhawk are very long and the legs are slender, making the success rate of preying on other small and medium-sized birds very high, so these two species of pine sparrowhawks are also called the nightmares of small birds, and many biologists have observed that the pine sparrowhawk flies around with the carcass of the half-eaten bird.
In the southern region of China, there is also a bird that can compete with the sparrowhawk, this bird of prey is called the crested eagle, its size is slightly smaller than the goshawk, and it is a more common bird of prey in the southern forest area of China.
Its body length can reach about 40 cm, and its weight can reach about 350 grams to 800 grams, but its tarsal feet and claws are thicker, because it has one or two protruding "dull hairs" at the back of the head, so it is called a crested eagle.
Crested eagles, like goshawks, belong to full-time hunters, flying in the sky and running on the ground, small animals are on top of their diets, but their favorite food is still squirrels, so every time the crested eagles fly over the forest and swoop, they can hear the screams of squirrels, and then you can see the crested eagles take off in the air, grabbing a squirrel on its paws.
Crested eagles have a fiery temper, they come and go in a hurry, they are very good at short-distance sneak attack hunting, known as small tigers in the forest, because they will also use branches and leaves to hide, and then see the opportunity to catch prey with lightning speed.
Because crested eagles and pine sparrowhawks overlap in their living areas, but pine sparrowhawks feed on birds in the sky, while crested eagles prefer rodents, there is no vicious competition between them.
It is hoped that human beings will protect nature, love nature, and make the number of these birds of prey recover quickly, and at the same time, they must also learn from Ke Zishuo children to be a serious and knowledgeable learner. The picture comes from the Network, and the intrusion must be deleted.
