An innovative project to ensure a healthy and peaceful coexistence between the people of Tromsø and the endangered Black-legged Kittiwake.
Black-legged Kittiwakes naturally breed in colonies on offshore islands, or in inaccessible areas of coastal mainland. Due to climate change, the Kittiwakes are now migrating to urban areas to breed.
Unlike its «cousins», the Herring Gull and the Sea Mew, who often find their food in the city streets, the Black-legged Kittiwake feeds on fish and shrimp found out at sea. It will not steal your hot dog.
The last few years, many Kittiwakes have nested on the building of the Tromsø Art Association, causing noise and disturbance, and damage to the building.
To avoid further damage, we have now built three installations, «kittiwake hotels», accompanied by various measures (wire, fire gel) for making the building itself less hospitable for nesting.
Movable tripods
The three tripod installations are mobile. They will at first be placed close to the building, to get the Kittiwakes to accept them. They will then be moved further down in the park, where the birds will be less of a nuisance. A larger permanent hotel is to be set up here.
Kittiwakes are nesting on the face of buildings throughout the city centre of Tromsø, and they will come back to nest in the safe surroundings of the city year after year. If the innovative project outside the Tromsø Art Association proves to be a success, the same measures can be applied in other parts of the city. Relocating of the birds from buildings to designated «nesting hotels» will help to ensure a healthy and peaceful coexistence for the endangered gulls and the people of Tromsø, while at the same time protecting the buildings in the city centre.
The project is a collaboration between The Municipality of Tromsø, The Norwegian Institute of Nature Research (NINA), The Tromsø Art Association, AT Architecture, and artists Lawrence Malstaf and Kåre Grundvåg.
Why do the Kittiwake move to urban areas?
For several decades, the number of Kittiwakes has decreased drastically. Climate change has led to nutrient failure, harsher weather conditions on the outer side of the coast, and increased predation. This has led to reduced reproduction and decline in the Kittiwake population. The Kittiwake’s way of adapting to the changes is to move their nesting sites to safer places. Cities and man-made structures have proven to be good options. For the species to survive, they depend on predictable and safe nesting sites. In cities, they get protection to give birth to their young.
About the Black-legged Kittiwake (Rissa tridactyla)
- Endangered seabird species in the gull family.
- White head and body, grey back, grey wings tipped solid black, black legs and a yellow bill.
- Feeds on fish found far out at sea.
- In Norway it breeds in colonies along the coast from the south-western part of Norway up to Finnmark, and on Svalbard.
- Due to climate change, the Black-legged Kittiwakes have migrated to urban areas to breed.
