From what I understand, one of the big bird issues with turbines is that birds of prey like hawks, eagles, and falcons don't generally look forward but down as they scout for prey, and thus are likely to fly into turbine blades. I believe some turbines have cameras systems to detect birds in the vicinity of the blades and either make a noise to alert the bird or maybe even bring the turbine to a halt. This is really only an issue for large scale installations though, obviously wouldn't apply to low lying roof installations.
