As colder years become more common, Alicante witnesses a striking spectacle: large starling colonies moving southward from other parts of Europe to escape the chill. At sunset, these birds lift into the sky in synchronized, graceful movements that resemble choreographed performances. The display fills the city with a living, moving sculpture, a scene some observers liken to a Hitchcock film, rich with motion and mystery.

Two species of these birds are common in Spain: the black starling and the common starling. The black starling remains in the Iberian Peninsula year-round, while the common starling is a winter visitor from northern Europe. Immigrants travel in flocks that form tight, evolving shapes as they descend and ascend, always keeping a compact silhouette, a phenomenon documented by the Spanish Society of Ornithology (SEO/BirdLife).
Unlike some other species, starling flocks follow no single leader. Each bird adjusts its movements in response to its nearest neighbors, creating a coordinated, collective dynamic. This aerial “dance” relies heavily on communication and rapid information sharing within the flock as they emit calls that help others position themselves in relation to the group.
SEO/BirdLife notes that these movements simplify foraging and help the flock avoid or confuse predators that roam the area. To predators, the shifting patterns make it harder to target a single prey. The starling formation is often likened to shoals of fish in how it confuses and distracts pursuing threats.
But why do these gatherings occur? Is it purely a winter phenomenon? The birds do not abandon their responsibilities during colder months, and the evening air shows with sunset become a familiar routine as many starling groups prepare to roost for the night. The spectacle features thousands of birds converging and weaving through the twilight skies before settling in. It is a display driven by energy, safety in numbers, and intrinsic flock mechanics rather than a singular purpose.

The beauty of this aerial show is tempered by practical concerns. Recreating the same city vista daily can be disruptive, and the constant, noisy flights may accumulate droppings that pose health and cleanliness challenges for residents. Managing these impacts requires thoughtful planning and cooperation between local authorities and communities.
