DTBird finishes first phase of a research program to improve the Collision Avoidance module
DTBird, in cooperation with the Spanish Wildlife Recovery Center (GREFA) and the Faculty of Veterinary Medicine of the Complutense University of Madrid, has completed the first phase of a research program focused on improving its bird collision avoidance system for wind turbines.
The project aims to develop more effective species-specific acoustic deterrence solutions based on bird hearing sensitivity research.
Research focused on bird hearing and species-specific deterrence
The research team tested the hearing sensitivity of several bird species, including Aquila chrysaetos, Falco naumanni, Gyps fulvus and Milvus milvus.
The objective of the study is to better understand how different bird species perceive sound frequencies and sound pressure levels. This information will help improve collision avoidance technologies used at wind farms.
Improving DTBird bird collision avoidance system
The audiogram plots obtained during the tests will help DTBird optimize:
- the acoustic frequencies emitted by the system,
- the sound pressure levels,
- and the location of the speakers installed on wind turbines.
The system configuration can also be adapted to specific bird species and turbine dimensions, helping increase deterrence efficiency while minimizing unnecessary acoustic emissions.
Scientific collaboration for wind farm biodiversity protection
The research program combines wildlife rehabilitation expertise, veterinary research and renewable energy technology development.
The collaboration between DTBird, GREFA and the Complutense University of Madrid supports the development of science-based solutions to reduce bird collision risk at wind farms while contributing to biodiversity protection.
Ongoing research program
The bird hearing research program remains open and may include additional bird species and individuals during future testing phases.
The information obtained in this first phase will support the next stages of DTBird’s collision avoidance system development.
