How did you know it was going to rain?

The following animals can predict the weather:

frog

In spring and summer, frogs croak loudly and densely, which indicates that it will rain soon.

2.swallows

When the weather turns bad, when it's going to rain, the air humidity increases, and the wings of bugs become soft, with small drops of water, and they can't fly. Swallows fly low to catch insects.

3. Sparrows

In summer and autumn, when the weather is sultry and the air is humid, sparrows feel itchy and fly to shallow water to take a bath to dissipate heat, which indicates that it will be rainy in a day or two. If a large group of sparrows take a bath, it indicates that there will be heavy rain in the future.

4.dragonfly

If you fly up and down in the air, there will be heavy rain in about 2 hours. Dragonflies circled thousands of times, and it rained in a few days.
