What causes swallows to fly low in rainy days?

Swallows fly low on rainy days mainly because the air is wet and their feathers are wet, so they can't fly high. As the saying goes, swallows fly low, snakes cross the road, and heavy rain will come soon. Not only do swallows fly low, but many natural phenomena can explain some weather changes in nature, and ants moving is also a phenomenon. So many friends will judge the weather according to the change or migration of some small animals. They look much smaller than humans, but they perceive the changes of nature faster than humans.

1. Swallows fly low in rainy days because their wings are wet. Many times, when it rains, they will find swallows flying very low. This is because when it rains, the humidity of the air will be higher, and the feathers can be wet before it rains. Then, wet feathers are a great burden and challenge for swallows to fly, so they usually fly low. This is also because the load does not allow them to fly too high.

Swallows fly very low in rainy days. In case of moderate rain or heavy rain, you can't actually see swallows flying outside, not only swallows, but also other birds. This is because when the rainfall is heavy, the rain is dense, which is not suitable for them to fly at this time. In most cases, they will choose a more suitable place to shelter from the rain, tidy up their feathers and knock off the rain on their bodies for the next flight. Therefore, it can be seen that swallows fly low, which can only be seen when it is about to rain or light rain.

Third, try not to disturb the swallow when it is sheltering from the rain. If you find a swallow sheltering from the rain by the window, try not to disturb it. At this point, its feathers can no longer support it to fly for a long time or distance. If it is frightened, it will fly again. Actually, it's very dangerous, so it's better not to disturb it as much as possible. Have you ever seen swallows fly low? Is it because it's going to rain?
