Flocking in sync — murmurations and starlings

One of the wonders of the Arch of Constantine is the murmurations that take place around it. A murmuration is a mesmerizing sight in which thousands of birds gather in the skies. The birds perform a graceful choreography around it, creating a visual spectacle that captivates onlookers. Starlings are the stars of this show. The scientific term for a starling flock is murmuratio. The birds fly in a swirling, mesmerizing pattern over Rome. Starlings perform the murmuration display to coordinate their safety from predators. The murmuration is a way for the starlings to keep safe in numbers. Watching a murmuration is a remarkable sight. At the peak of the performance, the starlings can completely cover the Arch of Constantine in a swirling mass. This orchestrated dance is particularly striking in Rome’s skies as the sun sets over the arch, creating stunning views.

Starlings in the city skies

Starlings are common birds in Rome. These winged thugs are usually tiny and well-camouflaged. They are often found in flocks across the globe and are known for their ability to change direction in an instant — the result of a combination of bird experience and social learning. They can even communicate alerts to the rest of the flock. In Rome, while the swarm passes over the city, and if an animal appears below, the entire swarm can dive down and strike the creature.

The science behind the swirl

Murmurations are the visual effect of information cascades. Each bird in a starling formation reacts to the movements of its closest neighbors. The swirling patterns exhibited by starlings flying in murmuration result from the birds’ ability to sense the direction in which nearby birds are looking. Birds in mururations have an innate sense of direction. Each bird knows the position of its nearest six neighbors, and swarms are coordinated by the flap synchronization of individual birds. The birds' wingbeats create the murmuration’s distinctive shapes. The interaction between the birds' rapid flight and the surrounding environment creates the illusion.

How birds flock

The murmuration is a phenomenon where birds coordinate their movements with incredible precision. The starlings’ synchronized flight patterns create a stunning visual effect. The movement of the birds is controlled by a set of rules that are based on the birds' individual flight styles. The birds follow each other with a very short time delay. The swarming behavior is a collective behavior that emerges from the interactions between individual birds. The flock moves as one unit, with each bird adjusting its position relative to its neighbors.

• Timing: The best time to see the murmuration is during early evening, when the birds gather to roost. This is usually around sunset. This is when the birds perform the most spectacular displays.
• Location: The Arch of Constantine is located next to the Colosseum. To get there, visitors can take the metro to Colosseo station or a bus to the Roman Forum stop. In the past, locals would encourage visitors to walk along the Via Labicana or Via San Gregorio to the archway. But recent safety advisories have warned to avoid moving around that area during times of reduced visibility.
• Equipment: Bring a camera with a good zoom lens to capture the birds in flight and any other wildlife that could be nearby. Also, carry a pair of binoculars, as the birds are quite high up and may be difficult to see with the naked eye.
