The black-legged kittiwake (Rissa tridactyla) is listed as endangered (EN) on Norway's Red List. The species is facing a high risk of extinction in the wild. Why are kittiwakes endangered? Climate change, overfishing and pollution contribute to this alarming situation. While kittiwakes disappear in the wild, some individuals find refuge in coastal cities like Tromsø, where predation is lower. ENDANGERED AND YET UNWANTED Sharing our urban spaces with kittiwakes brings challenges. For example, kittiwakes can be loud, and their droppings can leave traces on buildings and smell of ammonia. Contrary to a common belief, kittiwakes do not eat our food or waste. They exclusively forage at sea. But they need a structure to build their nest and raise the next generation of kittiwakes. Some building and business owners don’t hesitate to break the law and destroy nests during the breeding season. Others cover their buildings with bird deterrents, which – in the case of spikes – kill more kittiwakes than it deters. TICKING BOMBS Destroying an existing colony is not only a disaster for the birds. Once their former colony has been ruined, kittiwakes relocate, and often to buildings where there was no nest before. The former colony splits in several smaller colonies, and conflict spreads in the neighbourhood. KITTIWAKE HOTELS In Tromsø, the so-called “kittiwake hotels” are a successful example of alternative breeding sites, erected for kittiwakes in compensation for the destruction of their nests on buildings. These hotels are the result of a common effort between Tromsø municipality, bird scientists, and local architects and artists. THE KITTIWALKERS This is where Rissa’s volunteers enter! The Kittiwalkers survey the kittiwake nests in town from March to September. They are people who believe that coexistence is possible. They meet building owners, listen and inform, offer help and advice, and report illegal destructions if necessary. After receiving a short training, Kittiwalkers use Rissa's mobile app to survey the nests, and their observations are shared with key partners. Anyone can be a Kittiwalker and contribute to the cause in concrete ways. Kittiwalkers are citizen scientists, watchdogs and whistleblowers. Do you want to support the endangered kittiwake in Tromsø?
