Another prediction is that there might be a predatory bird involved with the case, experts
told The Guardian. Although no such bird is seen in the video, Dr. Richard Broughton, an ecologist with the UK Centre for Ecology & Hydrology is certain that a predatory bird was responsible for pushing the flock of birds towards the ground.
As seen in the video above, the birds descend from the sky as a unit, a phenomenon called "murmuration", often seen in starlings. Broughton is confident that the flock reacted to the predator in this fashion but was forced too close to the ground where some of them crashed, and never was able to recover. Even after the flock moved away, many birds can be seen taking to the skies from the ground.
Dr. Alexander Lees from Manchester Metropolitan University in the U.K. also agreed with this explanation and added that the
collision with infrastructure was quite common in birds.
