Raptors attracted to wind farms

Wind turbines offer great perching opportunities for birds of prey. From up there, they have commanding views of open spaces colonized by graminae, which attract prey such as mice, voles, rabbits, partridges, grouse etc.
First, they perch on still blades

Then they perch on nacelles or other parts:

Then they try to build a nest:
Osprey nest on wind turbine
In this case, a pair of ospreys succeeded because this turbine at Cape Vincent, NY, was mothballed.

Then they perch when the blades are moving:
See this video of a turkey vulture:
This perilous perching often ends up in loss of life.
But they also get struck while looking for prey or carrion below the turbines:

CONCLUSION: ornithologists hired by wind farm developers are misrepresenting the facts when they say that raptors “avoid” wind farms, or “are displaced” by them. The simple truth is that they are ATTRACTED, then KILLED by wind turbines. California’s very large Altamont Pass windfarm, for instance, kills about 1300 raptors a year, of which 116 golden eagles on average. – Source: “Developing Methods to Reduce Bird Mortality In the Altamont Pass Wind Resource Area” (pages 73 & 74, see last column: “adjusted for search detection and scavenging”) – Dr. S.Smallwood et al. (2004).
Would so many be killed if they “avoided” or “were displaced” by wind turbines?
