No disagree, its the availability of good hard facts to push back which interests me. The figures for Australian feral cats (6+ million) and the predation effects (billions) are so huge, it's hard to grasp sometimes.

We saw the same thing with solar thermal: "oh no the birds will fry" -well sure, some will. but compared to birds hitting glass towers, birds dying in other ways, feral cats.. not a biggie.

For specific threatened species, there are mitigations which have to be considered with wind towers. It's not nothing. But its functionally exceeded by the real risk.
