If you are aware of what is happening in Europe, you may have quickly guessed the answer. They escaped from the cold.
Thousands of starlings covered the sky of Rome, it was not a horror movie, they were birds looking for a little warmth.
Last week, the sky over Rome surprised all pedestrians and drivers by resembling a spooky scene from a horror movie.
Millions of little starlings covered the sky, returning in large numbers to the Italian capital seeking warmth and shelter from the icy eastern Europe and Scandinavia, the InverseScience portal reported.
Up to four million birds arrive in Rome each year, attracted by the warmth of the city in relation to the neighboring regions.
Every year
In recent years, the Romans have struggled to find a way to control swarming birds, as peregrine falcons, their natural predators, have been unsuccessful in grazing them.
Many residents have had to resort to trimming the trees in which the birds nest and blasting the cries of predatory birds over loudspeakers to scare away the starlings. Some have tried to use trained falcons to drive them away (not to eat them, their owners assured the press). Others scare them in a charmingly old-fashioned way: by banging on pots and pans.
