My long-term info from "a major windfarm" indicates very few actual blade
strikes. Most hits are involving guy wires on anemometer towers and the old,
guyed turbine towers. Like it or not, guy wires, because they are virtually
invisible at dusk and in fog, contribute greatly to the problem. Birds do
not hit monopole towers.
