This author has no idea what they are talking about- we have extremely high quality data on bird kills from wind farms. Teams of wildlife biologists literally walk the farms everyday identifying kills, and they have other teams that plant fake kills as experimental controls, to accurately quantify exactly the rate that kills are missed, and correct for that. This whole process is required by law, and there are a lot of wildlife biologists that do this work. You cannot operate a wind farm without quantifying its impact on protected species.
