Table 1.
List and description of spatial variables hypothesized to influence selection of nests by golden eagles.
Subscript denotes if multiple scales, quadratic terms, means and standard deviations, or if temporal lag effects of variables were modeled.
Fig 1.
North American Commission of Environmental Cooperation (NACEC) level II ecoregions Northwest Great Plains (NWGP; dark gray), and Wyoming Basin (WYB; light gray) portions of Wyoming, USA.
Reducing nest site data to remove redundant and clustered data produced 1,176 total nest sites, 483 in the NWGP and 693 in the WYB.
Table 2.
Best fit univariate term among competing variables in the Northwest Great Plains (NWGP) and Wyoming Basin (WYB), and coefficient estimate.
Asterisks denote correlated variables removed from multivariate RSF models.
Table 3.
Pairwise correlation values between variables used in global RSF models and best fit term associated with oil and gas development (producing wells within 5km).
Table 4.
Coefficient estimates and standard errors for global RSF models in the Northwest Great Plains (NWGP) and the Wyoming Basin (WYB).
Fig 2.
Resource selection function (RSF) probability grids across the Northwest Great Plains (NWGP) and Wyoming Basin (WYB) regions in Wyoming, USA.
RSF values represent the probability proportion to use of golden eagle nest site. Predictions are based on a global model for each region.
Fig 3.
Spatial delineation of overlay between seven NREL wind power classes (WPC; 1-low wind value, 7-high wind value) and regional resource selection function maps grouped into seven geometric bins (see Fig 4 for color legend).
Hatched areas are predicted low value for golden eagle nesting and wind development.

Area (km2) and the known number of nests (in parentheses) found overlapping cells between golden eagle RSF and NREL wind power class (WPC) map in the Northwest Great Plains (NWGP) and the Wyoming Basin (WYB).
Values on outside of tables represent the number of wind turbines in each category as of 2009. Cell colors correspond to map in Fig 3.
