Hi VilePlume,
One thing that is most obvious that stands out about that graph and the statistics in regards to exactly which types of birds are being killed and by what, is that it doesn't categorize the size ratio between which birds are being killed, and or which species, obviously cats kill lots of birds, but they are mostly killing birds with a wingspan of 12" or less, they aren't out putting a dent in the larger nesting types of birds like eagles, or other water fowl like ducks and so forth, the larger soaring types of birds are at most risk in regards to the wind turbines because the blades spin within their typical flight path and comfortable soaring/hunting height.
I had a friend that worked on these turbines as a mechanic in the past tell me one time, that they do find a lot of large birds like ducks, geese, owl's and eagles killed by the turbine blades, and there are other small flocking types of birds that are typically found nearby dead as well, not so much the forest tree nesting types though actually, because they have a smaller range and flight path/height and such.
My main point here is that household/feral cats aren't out killing off the larger species of birds, even crows are aren't really bothered by feral cats, I've never seen one really fear a cat either and we had lot of them flying all over the place at my Dad's old property and there were cats around, so yeah there's that part of the argument as well, most larger predatory birds aren't as effected as much by cats as the research/graphs might suggest, the largest birds I've seen most often killed by cats are dove birds, bluejays, and robin's, the smaller more agile species aren't really caught as often in my region (Been around cats for decades, they typically will choose a meal that is half there size or smaller, & I've seen chickens tear a cat up before).
And I might also include that a separate wildlife organization did a study on wind turbines and bird deaths and found a much higher number than is being reported, and this is from 6 years back mind you, we've added more turbines since.....
I'm far from being a Trump supporter, but he is right about the turbines, and some of the most protected species of birds are in danger from this type of technology, so I agree with him there, and I see a good bit of reason/evidence as to why he is right about the statements he made towards this issue.
