The Port of Barcelona completes the process of creating alternative roosts for cormorants

Three artificial roosts for cormorants established by the Port of Barcelona are now fully operational in the Llobregat Delta and its surroundings. In total, they provide places for around 600 individuals to rest overnight. Cormorants are large, gregarious birds that spend the winter in Catalonia. This is the culmination of a project started in 2006 to find alternative roosts to the former river mouth, and thus comply with the Environmental Impact Statement on accesses to the expansion areas of the major port infrastructure.

Each roost is comprised of various artificial structures designed by experts from MINUARTIA and the Port of Barcelona. The designs were selected after testing various models during the first years of the project. The sites at which the roosts have been installed were carefully selected to reduce the conflicts that these birds can cause, in particular regarding aviation safety at Barcelona-El Prat airport.

The last roost, which was completed in the spring, has been placed in an area that is included in the inventory of wetlands of Catalonia, and was installed with the collaboration of the Government of Catalonia’s Ministry of Territory and Sustainability and Molins de Rei Town Council.
