The sky of Rio in Patras was “blackened” by a swarm of starlings flying in formations. The spectacular spectacle was recorded on video.
As the elders say, when the starlings dance in the sky, it is a sign of cold and bad weather.
Starlings are quite social birds, we usually find them in very large flocks that often look like a cloud.
It is characteristic of the great sociability of this species is that, in their most basic everyday habits, starlings work in groups, as in migration, feeding etc.
