What are some examples of animals predicting the weather?

The low flying of swallows is a precursor to rain.

Sparrows can't fly far, always fly, sometimes fly high, sometimes fly fast, and it will rain in 30 minutes at 1 hour.

Cattle and sheep grazing in the wild don't go home when it is late. They always bend their heads and eat hard, and it will rain the next day.

Frog is an animal that sings with vocal cords. It makes sound by opening and closing two small bubbles on both sides of the head. If it is sunny, because the temperature is moderate and the air pressure is normal, the frog's cry is melodious and rhythmic; If the temperature rises when the heavy rain comes, and the temperature rises, making it difficult for the frog's vocal cords to make sounds, the frog will make irregular calls.

Ants migrate to high places in the forest. There will be heavy rain in three days. "When the ants move, the flood will come." "The ants are dry, and it rains cats and dogs." "Ants were running all over the ground, and the weather was fine that day."

Dragonflies, butterflies, bees, wasps, moths and other flying insects, if they are in a hurry during the flight, will fly east and west and flap their wings quickly, so it will rain in about an hour or two.

1. bees

Bees are social insects. A bee colony consists of three kinds of bees, namely queen bee, drone and worker bee. The queen bee and the drone are responsible for breeding offspring, and the worker bee is responsible for the daily life of the group, and the division of labor is very detailed. As the saying goes: "when bees are buzzing in the nest, heavy rain will come;" Bees never leave their nests, and the wind and rain are like a shuttle. "Vividly illustrates the behavior of bees and weather changes.

2.mosquitoes

Mosquitoes belong to Insecta of Arthropoda, and the common species are Culex pipiens, Anopheles and Aedes. Androgyny, male mosquitoes suck grass juice and female mosquitoes suck human blood, which can spread diseases. There is a folk saying: "Mosquitoes gather in the hall, and the Ming Dynasty wears a cloak; Mosquitoes bite people indiscriminately, and soon it will rain; Mosquitoes bite hard and it rained for three days. "

ant

Ants are insects of Insecta and Hymenoptera, and they are engaged in social life. There are more than 20 kinds of ants in a group, and ants are also very busy insects with complex behaviors. As the saying goes: "ants line up and it rains cats and dogs;" Ants moved, heavy rain rushed, ants ran with eggs, and heavy rain came. "

4. Spiders

Spiders are arachnids, a phylum of arthropods, with various kinds and web-forming behaviors. As the saying goes, "Spiders weave webs for eyes, while spiders draw webs for shade." Reveals the relationship between spider webs and weather changes.

magpie

Magpies are birds, passeriformes and ravenidae. Magpie is an auspicious bird in China. It is said that magpies nest on ancient branches. According to the author's observation, the nesting level of magpies has a certain relationship with the annual rainfall. If you see magpies nesting high, it will be rainy all year round. If you see magpies nesting in low-lying areas, it indicates that there is little rain all year round.

2. Chicken

Chickens are birds, galliformes. There are many kinds of galliformes in China, and domestic chickens are one of them. Domestic chickens live in nests. According to the author's observation, when domestic chickens sleep at night, the sleep phase of their heads is closely related to the weather changes. If their heads sleep outside, the weather will be fine. If the head of a chicken sleeps in, it will become rainy and rainy; If the head of a chicken is nothing more than nothing, the weather will be gloomy. The villagers also said, "The chicken climbs high and the sun shines."

mammal

Dogs are carnivores and canines. There are many kinds of dogs. Watchdogs are gentle and loyal to their owners, so there is a saying that "dogs don't think their families are poor". In recent years, some precious domestic dogs have become pets of the upper class, and their value has doubled, but the behavior of dogs is very complicated. Domestic cats are carnivorous, feline, intelligent and good at catching mice. As the saying goes: "dogs wash their faces, cats eat grass, and it rains in less than three days;" Dogs bite grass, cats bite grass and rain; The dog was lying in a pile of ashes, and it was raining. The relationship between two dynamic behaviors and weather changes is revealed.

Length pig. "There is grass in the pig's mouth, and the cold wave is coming." "Pigs build nests and it snows heavily." This is because the pig's nose and mouth are hairless, and it is in direct contact with the air. It is particularly sensitive to cold. Before the cold wave came, it had foresight and hurriedly took grass as its nest. When it's a little cold, stick your mouth in the grass. When it is colder, it will get into the grass to keep out the cold, and the sow's response is more sensitive. Therefore, seeing the grass on the pig street is a sign that the cold wave is coming.

2. dogs. The dog is soaked in water, and it's going to rain. Because dogs don't have sweat glands, they can't rely on pores to dissipate heat in summer, so they can only keep constant temperature by opening their mouths and pulling their tongues to dissipate heat. When your mouth and tongue are useless, jump into a pond or stream to soak in water to help dissipate heat. So finding a "dog in the water" indicates that it is going to rain. When it is cold, the dog crouches on the haystack and uses his mouth as a "heater" to warm his navel, which indicates that a cold wave is coming.

3. Toad. Toad is also an expert in prediction. Its physiological structure is special, its lungs are like football, and its breathing ability is not great. It is impossible to absorb enough oxygen by such lung breathing alone. So toad has to rely on his skin to help him breathe besides his lungs. There is a condition for breathing through the skin, which is to keep the skin moist frequently, so that the oxygen in the air can be dissolved in the mucus of the skin first, and then enter the blood from the skin. If the skin is dry, you can't breathe and it's hard to live. So it is very afraid of strong light and dry weather, hiding in the dark during the day and coming out for food at night. Before the rainstorm (about 1 day), the air humidity is high, and it also comes out during the day. This abnormal performance is in line with the folk proverb "When a toad comes out of a hole during the day, it will rain".

4. fish. Fish live by breathing oxygen dissolved in water. On sunny days, when the atmospheric pressure is high and there is a lot of dissolved oxygen in the water, it quietly sinks to the bottom; Before it rains, the air pressure is low, the oxygen in the deep water is greatly reduced, and the fish float to the surface to breathe, so there is a saying that "when a fish dives, it will rain".

5. swallow it. There is a folk saying that "it will rain when swallows fly low". This is because swallows eat worms. When it rains, there is a lot of water vapor in the air, which makes some insects' wings wet, just like the plane is too heavy to fly, but it still has to fly and can only fly against the ground. Secondly, when the weather turns rainy, the air pressure will become lower, the water vapor in the air will increase, and some insects in the soil will crawl out of the soil. When it is swallowed, it will fly very low to catch insects to eat.

6. snakes. Most snakes hide in caves during the day and go out for food, water, bathing and molting at night. However, when the weather is particularly humid and sultry, holes will also be forced. Therefore, it is a sign of rain when a snake comes out of the hole during the day, especially in late autumn and early winter. It is already cold, and when a big snake comes out of the hole, it will rain in a day or two. It is the verification of "the big snake comes out of the hole and it rains" and "the snake gallery rains".

7. Chicken. "The chicken stayed late, and it was rainy." Chicken has no sweat glands and sebaceous glands, so it has insufficient heat dissipation ability and is very afraid of heat. The suitable temperature for adult chickens is 20℃. If it exceeds 30℃, always open your mouth and spread your wings to help dissipate heat. In the hot summer evening, it was even more stuffy in the chicken coop, so it was found that the chickens had been reluctant to enter the coop for a long time, which was a sign that a thunderstorm was coming.
