How can some animals predict the weather so accurately?

Frogs predict the weather in spring and summer. Frogs croak loudly and densely, which indicates that it will rain soon. The proverb says, "When a toad shouts loudly, there will be heavy rain".

Before the weather forecast is going to rain, the air pressure is low and the humidity is high, insects are flying close to the ground, and chickens are looking for food for insects. In addition, the cage is stuffy, and chickens don't want to enter it. As the saying goes, "chickens are worried about the rain, ducks are worried about the wind."

Ants predict the weather. Ants came out of the hole in droves, which indicated that heavy rain was coming. As the saying goes, "ants are in droves, but it won't be sunny tomorrow."

Spiders predict rainy days, such as rising air pressure, decreasing humidity, insects flying high, and spiders will open their nets to catch them, indicating that the weather will clear up. On the contrary, the spider closes its net, which indicates that it will rain.

Termites predict the weather in spring and summer. Whenever the weather is sultry, termites fly out of the cave. I didn't know the way back to the cave at night, so I pounced on the light, which indicated that it would rain heavily in a day or two.
