NEW DATA ON CAUSES OF DEATHS

In an interim report from Kenetech's team of bird researchers, the Avian Research Program Update, it is revealed that the company's Model 33M-VS is substantially less dangerous for raptors than the older Model 56-100. New studies, to be completed in 1995, encompass controlled tests of six types of patterned coloured blades and pylons or markers. Increased visibility of blades and lower speed seem to be key factors in reducing collisions. The studies carried out so far in Spain and at the Altamont Pass have been too small in sample size to be statistically significant.
