In the Dnieper on the left bank, the birds almost completely covered the sky
A huge flock of starlings covered almost the entire sky on the Klochko-6 housing estate in Dnipro, reports "Vidomo" with reference to "Truha Dnipro".
This phenomenon is called murmuration.
Murmuration is the phenomenon of coordinated flight of a large flock of birds (starlings, jackdaws, crows, etc.), forming dynamic three-dimensional figures of variable density.
Computer modeling helps to understand how the behavior algorithm of an individual bird leads to a similar phenomenon.
