Jim Wiegand — The Truth about Wolfe Island bird mortality rates

By using mathematical formulas derived from these studies, the average distance of a large bird carcass found under the 2.3 MW turbines at Wolfe Island would be 101 meters from their towers. The Wolfe Island mortality studies used search areas of only 60 and 50 meters. These studies missed most of the carcasses.

Here is a little more proof about how the Wolfe Island Mortality studies were designed to find only a fraction of the birds killed by their huge turbines. This information is very important so the public can understand the true character of the wind industry.
Mortality studies years ago at Altamont pass showed that large bodied carcasses like ducks, hawks, and eagles were found at an average distance of 57 meters from much smaller turbines. These turbines had a tower or hub height of 32 meters with a rotor diameter of 33 meters. The huge 2.3 MW turbines at Wolfe Island have a tower or hub height of 80 meters with a blade diameter of 101 meters. The placement of hundreds carcasses found under different sized turbines, showed an increase in distance from turbines with an increase in their size.  More...  [Quixotes Last Stand]

Can someone verify that the mortality studies conducted at the Wolfe Island project actually only encompassed 50 -6o meters from the tower?

This seems like an incomprehensible oversight or failing of the study, practically unbelievable. If they found dead birds at 75 meters or farther, from the tower how did they explain them, or did they truly just not count them.

Where could one find an actual account of the study methodology, to bear this out?

Go over there and count the dead birds stupid.
