"The little swallows wear flowery clothes and come here every spring." When we were young, we often heard this nursery rhyme. In our impression, swallows are migratory birds. In winter, swallows will fly south to spend the winter. When spring comes, they will fly back.
Many people only know that swallows will fly south through the winter, but they don’t know why they fly to the south. It turns out that they are also foraging. Basically, all swallows only prey on invertebrates in the air, mainly insects. In northern my country, when winter comes, the temperature drops sharply, and the insects flying in the air have decreased. The swallows have no sufficient food, so they can only fly to the warm areas in the south to find food.
However, nowadays, the climate is changing rapidly, and spring and autumn are getting shorter and shorter. Often after winter, summer comes, autumn is not enjoyable, and winter comes overnight. Especially in northern cities, the temperature drops sharply and even snowflakes float, which makes the swallows seem to have time to react and make sufficient preparations. The cold winter comes.
Recently, a woman in Jilin took an interesting video. She said that it was snowing here and the weather was very cold. Unexpectedly, the swallows that flew to the south early to celebrate the winter in previous years were full of telephone poles, and they looked dense. She couldn't help but guess: Is the weather changing too fast, and they didn't have time to fly to the south too much?
Coordinate is a place in Jilin. In the picture, the sky is gloomy and gray. Two parallel telephone poles in the distance are filled with black swallows, neatly, just like dried salted fish worn with ropes, which is amazing and spectacular.
The woman couldn't help but ask curiously: Cute little swallow, are you having a meeting here? Why don't you fly back to the south quickly?
According to the woman, in their local area, winter came into the first snowfall, and the weather suddenly became much colder. It can be seen that the eaves were covered with white snow.
She walked in the snow and looked up suddenly, but found a large number of swallows parked on the telephone poles, lined up in black, quite spectacular.
There are also swallows resting on the eaves. The woman couldn't help but sigh: I suddenly switched to winter mode, and I guess the swallows didn't adapt and didn't have time to fly south.
When netizens saw this strange and spectacular scene, they couldn't help but leave messages, saying that this summer passed and winter ended and summer was summer. Spring and autumn were so short that even the little swallows couldn't figure out the alternation of the seasons.
A netizen said it was very funny. He said that he wouldn't be confused. Just like me, it was still 28 degrees a week ago and 16 degrees at night. Unexpectedly, after the cooling down, it became less than 10 degrees, and even people couldn't adapt.
Netizen's smart Yingbao : This is Swallow in a meeting! Believe me, because whenever this scene occurs, one of the swallows will disappear the next day. My mother said they are just meeting and appointment time.
Some netizens also said anxiously: Little swallow, fly quickly, you can’t eat after the snow.
Author's opinion:
Indeed, it is the first time that the author has seen a large cluster of swallows like this.
Maybe they are gathering together and are planning to fly south. Unexpectedly, the plan has not changed quickly. Winter has begun overnight and before they can set off, the heavy snow fell. Changes like
are also related to the impermanence of climate change. Small animals are actually the most sensitive perceivers in nature. Climate change is abnormal, and animals are often more sensitive than humans. For example, the saying "The duck prophets when the spring river is warm" is a very vivid realistic scene.
People have compassion. Like humans, animals are living creatures living on the earth. loves the earth to protect our homeland, and everyone should be responsible.
