Results of the latest evaluation of DTBirdV4D4 in Sweden

In 2015, Ecocom AB (now a part of Calluna AB), in collaboration with Vindform, initiated a pilot project to install and evaluate the DTBird® bird collision avoidance system under Swedish wind farm conditions.

The project focused on analyzing bird detection capabilities, collision risk reduction and avoidance behaviour around wind turbines.

Evaluation of the DTBirdV4D4 bird collision avoidance system

The evaluation demonstrated that the DTBird system is effective for bird detection and enables species identification for large and medium-sized birds.

The study also showed that the system reduced bird dwell time within collision risk areas by between 61% and 87%, especially for large bird species.

Bird avoidance behaviour near wind turbines

The DTBird bird collision avoidance system triggered avoidance behaviour in 88% of cases where birds were on a collision course with wind turbines.

An individual observation of a White-tailed Eagle (Haliaeetus albicilla) also confirmed visible avoidance behaviour near the turbine.

Environmental monitoring and biodiversity protection

The Swedish pilot project provided valuable operational experience regarding bird monitoring and biodiversity protection technologies for wind farms.

Environmental monitoring systems such as DTBird help wind farm operators improve wildlife protection strategies while supporting renewable energy development.

The video showing White-tailed Eagle (Haliaeetus albicilla) collision avoidance behaviour is available on the DTBird YouTube channel: DTBird Collision Avoidance: White-tailed Eagle.
