The spring messengers of the spring, besides the snowdrop, are clearly the storks and swallows. But there is a "little" beauty mist. Maybe we can't enjoy swallows long?
In the spring, the birds, the swallows, will come to us with the charming small but larger distance. Every year, professionals complain, and maybe you have already noticed that fewer and fewer people are flying around the end of the summer, despite the supply of new ones.
If we take into account only the last ten years, we get the data that the number of smoke flies dropped by nearly 45%, while that of the molar swallows by 65% !!! The decline has been not only seen in the last 10 years, but it has been a constant one, but if this rate is kept down by the decline in their number, we can soon get to the point where holiday and poop swallows in our country disappear completely.
The reduction in the number of swallows also plays a role in how humans treat birds. Sometimes they try to build a nest that is not suitable for people, so they simply crush their nests. Of course, there are also a lot of swallow-haired people, but environmental pollution, inadequate waste disposal also reduces the number of swallows. This is a problem not only in our country, but worldwide.
