Can animal behavior predict the weather?

Yes, give some positive examples: Spider: I saw water droplets on the spider's web this morning, and it will be sunny today. Because on sunny days, the temperature difference between day and night is relatively large, and the warm and humid airflow will condense into small water droplets when it is cold. On a sunny afternoon, if spiders make many webs, it will rain for the next day or two. If the net is solid, the wind and rain will be bigger, otherwise, it will be smaller. Netting after rain means it will clear up.

Frog: On the eve of rain, the air humidity increases, and the frog's sensitive skin will feel it immediately. Perhaps for fun, on the eve of rain, frogs will keep chirping, and the volume is higher than usual. Before the weather turned to rain, the humidity in the air was high, the frog's skin was moist, the frog croaked little and the frequency was low. When the storm comes, we can't hear frogs. But on sunny days, frogs will bark loudly.

Earthworms: Earthworms get out of the ground, which means it will rain today. Because earthworms breathe through the skin, too dry air is not conducive to their capture of oxygen. On the eve of rain, the air humidity increases, and earthworms will be happy to get out of the ground. If earthworms crawl out of the ground in spring and summer, heavy rain often comes. When the weather gets worse, the humidity increases and the ground gets warmer, earthworms will drill out of the ground.

Dragonfly: When the dragonfly flies low, it will rain. Before it rains, the low pressure makes insects close to the ground. Dragonflies feed on small insects. Dragonflies must fly low in order to eat food.

Ant: When heavy rain comes, ants will move their homes to higher places. Therefore, when they see ants moving, it often indicates a heavy rain.

Snakes: Snakes are very sensitive to air humidity. Like ants, snakes will move from low places to high places before it rains.

Swallow: Swallows open their mouths to catch insects in the air when flying. On the eve of rain, they can only fly low to eat insects for the same reason as dragonflies. When the weather gets bad, most insects fly on the ground. Swallows want to eat insects, so they fly very low. Note: The statement that swallows fly low and dragonflies fly low and rain is not necessarily correct. This phenomenon can only show that the air pressure is low and sometimes it doesn't rain.

Fish: In the summer evening, if there is a "diving" phenomenon in the fish pond, it indicates that there will be a thunderstorm.

Chickens and ducks: Chickens return home early, and the next day is usually sunny. On the contrary, if you enter the cage when it is getting dark, the weather will get worse. Ducks and chickens behave in the opposite way. Ducks are animals in love the water, and the early arrival of ducks in cages means that the weather will turn bad. On the contrary, the next day will be sunny.

Cat: Cats wash their faces with their front feet because when it rains, the humidity increases and fleas move on cats. Note: cats love to clean and wash their faces even if it doesn't rain.
