Horrifying 'storm' black sky of England

Thousands of starlings on the way back to Gretna. Every year, a large number of starlings fly back to Britain from Russia and northern Europe to avoid cold weather. Unfortunately, this phenomenon in the UK is no longer popular.

Scientists believe that these starlings fly in flocks for safety purposes, to keep them warm and make contact with each other.

There are many birds that have been poisoned when flying into the UK, and as a result, the number of flocks is greatly reduced.

In the afternoon, they often create unknown shapes in the sky.

These birds are usually gathered from November every year. The number of children in the herd remains the same until spring, when they start to pair.

There are many flocks, the number of birds can be up to 2 million.
