Effects of Wind Turbines on California Condor in Baja and Beyond

Two species of particular concern for proposed wind turbine projects in Baja, Mexico are the golden eagle and the reintroduced California condor, both protected species.

The main objectives of this research are to investigate the spatial and behavioral ecology of these species and identify ways to reduce or avoid potential impacts.

We will design and implement a program to establish movement patterns and habitat utilization of resident golden eagles and California condors reintroduced in northern Baja California, with a focus on areas proposed for wind project development. Our work involves nest searches and monitoring, capture of eagles and application of transmitters, radiotelemetry of eagle and condor movement behavior, and computer modeling of nesting and feeding territories to delineate high use areas.

We will also measure and determine interrelationships among habitat, topography, wind, temperature, and flight behavior.

By evaluating the movements of golden eagles and condors while identifying the conditions associated with high use, we will be able to pinpoint areas of increased risk of mortality posed by wind turbines and provide a better risk assessment.

Finally, techniques to modify and incorporate the monitoring of condor movements into the operation of wind turbines that present the greatest risk will be investigated to limit turbine-related mortalities.
