If you read the link that also appeared in my post, you'd see more detail and a bit more meat about the responsible siting of wind turbines from the RSPB:
The available evidence suggests that wind farms can harm birds in three possible ways – disturbance, habitat loss or damage (both direct or indirect), and collision. Poorly sited wind farms have caused some major bird casualties, particularly in Tarifa and Navarra in Spain, and the Altamont Pass in California. At these sites, planners failed to consider adequately the likely impact of putting hundreds, or even thousands, of turbines in areas that are important for birds of prey. Tragically, killing many hundreds of birds as a result.
If wind farms are located away from major migration routes and important feeding, breeding and roosting areas of those bird species known or suspected to be at risk, there is a strong possibility that they will have minimal impact on wildlife.
Which seems robust enough to cover what the graphic didn't.
