Question: Are there any wind turbine manufacturers advertising claims
that their products do not contribute to bird mortality? If so please
compare & quote their claims and post links.
   
A previous question: WIND ENERGY question 
 Question ID: 120272 

brought forward a great (and quite interesting) answer and could
narrow the search somewhat.

This is a ducted fan wind turbine:

SAFE, SILENT, VIBRATION FREE
The LIM is totally silent and produces no vibration. The
intake and exhaust apertures can be screened to protect
birds and butterflies from the fan rotation.


Search strategy: I found the above web site while working

Our vertical axis units are easily installed, may be painted to blend
with the landscape, produce no noise or vibration, and are animal
friendly. Birds use obstacle recognition to detect objects while in
flight. Birds that encounter our units fly around the unit avoiding
any collision.
