The model DTBirdV4D8 has been installed in the Wind Farm Terna, in Thrace (Greece) under the project LIFE12 BIO/GR/000554. This project aims to demonstrate the practical application of post-construction assessment and post-construction mitigation. DTBird was already participating in the LIFE project with the model DTBirdV4D4 that started operating at the Wind Farm and the Park of Energy Awareness (PENA) of CRES at Keratea (Greece) at the beginning of 2016.

Two DTBirdV4D8 units are operating with Collision Avoidance module D8 (8 speakers distributed at 2 heights, below the lower point reached by the blades and below the nacelle). Each unit has two settings (sound activated/muted) which switch from one to the other every week. Every week, one unit has the sound activated while the other is muted.

The wind farm is located in Castilla y León (Spain) and the most frecuent species detected in the vicinity of the wind turbines are: Gyps fulvus, Milvus milvus, Buteo buteo and Falco ssp.

The collected data will be used for the species specific evaluation of the DTBird Collision Avoidance module.

DTBird in cooperation with the Spanish Wildlife Recovery Center (GREFA) and the Animal Medicine and Veterinary Surgery Faculty of the Complutense (Spanish University) has tested the hearing of the following bird species: Aquila chrysaetos, Falco naumanni, Gyps fulvus and Milvus milvus.

The Audiogram Plots of these species will be used to create new species-specific collision avoidance sounds and to adjust the design of speaker's location and sound levels emitted, customized for both target species and wind turbine dimensions. The bird's hearing research is still open to add more species and individuals.

We have filed orders for 35 units of the models DTBirdV4D4, DTBirdV4D8, DTBirdV8D10, DTBirdN2 (Night Detection model) and DTBatD3, to be installed in France, Greece, the Netherlands and Spain.

In 2015 Ecocom, in collaboration Vindform, initiated a pilot project to install and showcase the DTBird system, and to evaluate how the DTBird system performs under Swedish conditions. The report (in Swedish) can be found in the following link: Pilotinstallation av DTBird-systemet i Sverige Möjligheter med skyddssystem för fågelfaunan vid vindkraftanläggningar – erfarenheter från Sveriges första installation av DTBird. Ecocom AB. Amongst others it includes the following results:

The system is viable for bird detection and enables species' identification of large and medium-sized birds.
The system offers effective protection above all for large birds by reducing their dwell time in the risk area between 61-87%.
The system triggers avoidance behaviour in 88% of cases where the bird is on a collision course with the wind turbine. An individual observation was performed for the White-Tailed Eagle (Haliaeetus albicilla) where the avoidance behaviour was noted as well.
The reports' sumary was translated to English by DTBird in the link: Experiences from Sweden's first DTBird instalation. Ecocom AB.

The video of the White-Tailed Eagle (Haliaeetus albicilla) collision avoidance is available in DTBirdteam Youtube channel: DTBird Collision Avoidance: White-tailed Eagle.

Although DTBird research program started in 2005, in Mach 2009 the first DTBird unit was installed at a wind turbine of Sammca Group, in Spain. Currently over 90 DTBird&DTBat units are distributed in 11 countries.
Ever since, DTBird has been under continuous evaluation, research and improvement process with incomes from scientists, computer engineers, ornithologists and veterinarians from many countries. Current DTBird specifications can be found in the link: DTBird System Specifications for Wind Turbines. February 2017.
