Reporting of Monitoring Results

 

Pre-construction and post-construction survey results should be reported to the Service’s Wyoming Field Office at least annually. In coordination with our office, survey methods may be modified if wildlife conflicts are identified (e.g., high concentration of eagle activity). Once pre-construction surveys have been completed, use pre-construction data to refine project siting (e.g., micrositing of turbine layout, roads, transmission lines) and minimize wildlife impacts.

Pre-construction reports should include:

  • Description of methodology specific to area surveyed;
  • Species identification and temporal and spatial use patterns (including important bird habitats);
  • Locations of raptor nest/eagle roost locations (maps and UTM coordinates) and activity;
  • Analyses and maps of avian behavior, including flight heights;
  • Maps and GIS shapefiles of important habitat, including terrain features and foraging areas; and
  • All other pertinent data presented in formats as recommended by the Service’s Wyoming Field Office.

Post-construction reports should include:

  • UTM locations and species identification of all fatalities;
  • Avian fatality by turbine location for the current year and compared to previous years;
  • Estimated/observed mortality rates compared to predicted fatality rates;
  • Relationships of bird fatalities to site characteristics;
  • Composition of migrant versus resident species’ fatalities; and
  • Evaluation of fatalities to determine how project management and/or operation could be modified to minimize further mortality.
  • Activity of raptor nest sites and status of important bird habitats
  • All other pertinent data presented in formats as recommended by the Service’s Wyoming Field Office.

Record individual mortalities and report, as directed, to Service Law Enforcement with the following information:

  • Species identification, age (adult or immature), and gender, if possible;
  • Location of the mortality (e.g., GPS location, turbine/utility pole number);
  • Condition of the mortality (e.g., fresh kill, broken wing);
  • Band or tag number if applicable; and
  • If raptors mortalities are noted, we recommend that a digital photo of the scene be included. Do not move the bird until the Service’s law enforcement officer has been contacted, as there may be specific guidance based on the situation.

Report all eagle mortalities and take of threatened and endangered species to the Service Law Enforcement within 24 hours (in eastern Wyoming contact 307 261-6365 or in western Wyoming contact 307 332-7607). If they are unavailable, contact the Wyoming Field Office (307 772-2374).

The Service has an on-line system for electric utilities to report bird electrocutions or collisions. We encourage electric utilities associated with wind energy facilities to utilize this system at https://birdreport.fws.gov/BirdReportHomePage.cfm.
