Forecast weather about animals, such as animal behavior before rain.

Before it rains, most insects, birds and some aquatic animals will have special reactions.

The following are the contents of abnormal animal behavior and weather changes, which I hope will be useful to you:

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.
