What happened to the animals before it rained?

Before it rains, small animals behave as follows:

1, bees return to their nests

On rainy days, bees will hide in their nests and will not go out to collect honey. Because when the humidity in the air increases, the wings of bees will become wet and heavy. Similarly, cicadas (cicadas) will call by the vibration of their wings. When the weather is wet, cicadas will be quiet.

2. The turtle shell is wet

Before it rains, the turtle's back shell will become wetter and the pattern on the shell will be darker, because the turtle is lower from the ground and its shell is smoother. When warm and humid air that causes rainfall flows, water droplets will form on the turtle's back shell.

3, ants move

Before it rains, ants will leave their nests on a large scale and move to higher ground. Because ants live underground and are sensitive to air humidity, when the air humidity rises, the nest will become damp and uninhabitable, so ants will leave the nest on a large scale

4. Earthworms are on the road

Earthworms will go out in large numbers before it rains, because earthworms love humidity. Before it rains, the air humidity becomes higher, and the gap between the humidity outside and the underground narrows, so the earthworm goes out to move.

5. Goldfish surfaced.

Because there is not enough oxygen in the water when it is about to rain, goldfish need to swim out of the water to breathe in.

6. Swallows fly very low

Swallows fly low because when it is about to rain, the wings of insects feel wet, so they fly low, and swallows fly low, too, in order to hunt.

7, the chicken does not enter the nest

Chickens don't have sweat glands, and it will be sultry before it rains, so they don't want to go into the henhouse and want to stay in a cooler place.

8, toad out of the hole

Toad can feel the humidity in the air before it rains, so he will climb out of the cave and wait for it to rain.
