Automatic Bird Monitoring & Protection
DTBird® is a self-working System for Bird Monitoring and/or Mortality Mitigation at On&Offshore Wind Turbines (WTG). The system automatically detects birds and can optionally take two independent actions to mitigate bird collision risk: the activation of warning sounds and/or the stoppage of the WTG.
Detection/Collision Control Module
Daylight HD cameras survey 360º around the WTG. Optionally, at night 2-8 Thermal cameras survey the monitored areas around the WTG. Birds are detected in real-time while videos and data are stored. Installation design and operational settings are customized for any Target Species and WTG dimensions. Potential and accidental bird collisions can be recorded and checked in videos with sound through Online access.
Collision Avoidance Module
This module automatically emits warning sounds at birds flying in potential collision risk and discouraging sounds for birds flying in the high collision risk area. The type of sounds, emission levels, and installation and operational settings are adjusted to: target species, WTG dimensions and local sound regulations. No energy production loss and applicable to all bird species. Species-specific sounds can be applied.
Stop Control Module
Automatic WTG stop and restart according to real-time bird collision risk evaluation. Adjustable to target species/groups.
Data Analysis Platform
Online Data Analysis Platform provides transparent access to review bird flights including: videos with sound, environmental data and WTG operational parameters. Graphics and Automatic Service Reports for selected periods are also available. Includes three access right levels: Analyzer, Viewer&Reporter and Viewer.

DTBird in cooperation with the Spanish Wildlife Recovery Center (GREFA) and the Animal Medecine and Surgery Veterinarian Faculty of the Complutense (Spanish University) has tested the hearing of the following bird species: Aquila Chrysaetos, Falco tinnunculus, 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.
