USGS Northern Prairie Wildlife Research Center
It is well known that North American grassland bird populations appear to be declining (Igl and Johnson 1997, Sauer et al. 2004). Most of these birds breed and winter in North America, so declines are likely associated with continental processes (Knopf 1994). Scientists have also observed parallel declines among species that have overlapping breeding ranges but disparate wintering distributions (Igl and Johnson 1997). These patterns suggest declines may be linked to problems on the breeding grounds.

Fields Of Opportunity: Wind Machines Return To The Plains, Jacob Sowers
Great Plains Quarterly
The last two decades have seen a rebirth of wind machines on the rural landscape. In ironic fashion the wind's kinetic energy has grown in significance through its ability to generate commercial amounts of electricity, the commodity that a few generations earlier hastened the demise of the old Great Plains windmill. Yet the reemergence of wind machines on the landscape has been slowed by local opposition. Many places across the country have seen resistance to the construction of vast wind turbine arrays. Although wind energy fulfills both the businessman's requirement for profit and the environmentalist's desire for clean electrical production, …
