Avian Assessment

  • Raptor Electrocution Risk and Mitigation Studies
  • Avian Protection Plans
  • Bird Collision Risk and Mitigation Studies
  • Animal-caused Outage Mitigation Studies
  • Litigation Support
  • Product Testing
Since 1982, the environmental consulting and research team has worked with utility companies and regulatory agencies to identify and solve wildlife and avian-related issues, both nationally and internationally. 

Technical specialties include:
  • Avian Electrocution Studies and Risk Analysis
  • Avian Collision Studies and Risk Analysis
  • Avian Protection Plans
  • Transmission Line Bird Streamer and Contamination Outage Studies
  • Substation Outage Investigations
  • Animal-Caused Outage Studies
  • Nest Management
  • Migratory Bird Treaty Act Permitting
  • Litigation Support
  • Utility Product Testing
  • Training and Workshops
An integral part of this process is identifying problem areas, specifying applicable retrofits for existing facilities, and developing effective approaches for new construction.  Retrofitting recommendations are combined with a review of existing utility design standards to ensure new electrical facilities are constructed to bird-friendly standards.

EDM actively partners with utility manufacturers to test new products to reduce animal electrocutions and bird collisions.  EDM has the capability to safely test products with live animals in a controlled setting. 

Scientific research is a critical part of EDM’s wide range of capabilities.  EDM has helped develop the Bird Strike Indicator (BSI) to remotely detect and report collisions.  This technology is licensed to EDM for use on overhead lines or guy wires.  Other current research projects include developing a repellent for woodpecker damage control, commercializing a spray-on insulation to mitigate animal contacts with power lines, testing a sonic dissuader to deter woodpeckers from dangerous utility poles, and testing the feasibility of a remote bird and bat collision sensor for wind turbines.

EDM often incorporates and combines biological and engineering capabilities.  For example, EDM engineers recently evaluated bird collision marking devices, tested and recommended by the Environmental Services Group, for their possible electrical interference on high voltage power lines.
