Given the potential for wind energy development <br />and high biodiversity in the Southern Blue Ridge <br />Ecoregion, it is not surprising that a number of <br />groups have taken an active interest in understand- <br />ing the impacts of turbines in western North Caro- <br />lina. Over 200 avian species breed or regularly occur <br />as migrants or winter residents in the Southern Blue <br />Ridge (Lee et al. 1985, Hunter et al. 1999). The <br />NC WAP has identified 46 avian species in this <br />region as SGCN, 16 of which have state listing status <br />(Special Concern, Significantly Rare, Threatened, or <br />Endangered, Table 4 -6). In addition, the Southern <br />Blue Ridge Ecoregion supports 12 endemic species, <br />including subspecies such as Southern winter wren <br />( Troglodytes troglodytes pullus ) and Appalachian <br />ruffed grouse (Bonasa umbellus monticola; Lee and <br />Browning in prep. in Smalling 2003). Many of these <br />are restricted to higher elevation areas that may be <br />potential wind sites (Smalling 2003). <br />Of particular concern in this region is the large <br />number of neotropical migrants that pass through <br />the area on the their way to, or back from, breed- <br />ing grounds. Raptors in particular are known to <br />use the Appalachian corridor for migration (Small- <br />ing 2003) and can be disproportionately affected <br />by wind turbines, particularly if they are sited along <br />ridge lines. Along migration corridors, raptors will <br />often fly directly above the ridges and tend to hug <br />the ridges in flight as wind speed increases (Van Fleet <br />and Small 2010). Specific raptors of concern for <br />North Carolina in this region include Cooper's hawk <br />(Accipiter cooperii), sharp- shinned hawk (Accipiter <br />striatus), Northern saw -whet owl (Aegolius acadicus), <br />peregrine falcon (Falco peregrinus), and American <br />kestrel (Falco sparverius).
