Dublin swans hit bridge cables

Andrea Porter of Kildare Wildlife Rescue called recent swan collisions with the Samuel Beckett Bridge "fairly catastrophic." The structure, which links Dublin's north and south banks, has become a hazard for the large birds.

The bridge opened in 2009 and features a distinctive harp shape. While many visitors praise the design, Porter said the diagonal cables pose a specific danger. Swans have eyes on the sides of their heads, which limits their forward vision. They often fly straight into the wires without seeing them.

In the past four years, rescue teams have documented at least 17 swans that died after hitting the bridge. Porter suspects the true number is higher because many incidents go unreported. She noted that swans can weigh up to 15 kilograms and fly at speeds near 88 kilometers per hour. The combination of weight and speed makes the impact severe.

Porter said the rescue group is collecting data to identify patterns in the crashes. She has observed that many injured birds are found around high tide. When the water rises, the space beneath the bridge shrinks. Birds may then choose to fly over the structure instead of under it, increasing the risk of hitting the cables.

The rescue team wants to determine if the collisions happen when swans are flying into the city from the Greater Dublin area or when they are taking off from the water. Other factors, such as light conditions and specific flight paths, also play a role. Porter said the team needs this information to understand when and why the accidents occur.

With the data in hand, Kildare Wildlife Rescue plans to approach engineers. The goal is to find a solution that addresses the visibility issue for the birds. Porter described the bridge as beautiful but emphasized that the current design is difficult for the swans to navigate safely.
