Stupid question, I know, but those turbines always look like they are moving super slow. Are there sudden burst of speed that are causing all these birds to get chopped up? Or are birds just flying full speed into the sharp angle of the blade?

Depending on wind conditions, the blades turn at rates between 10 and 20 revolutions per minute. Considering the length of the blades with average wind speeds of 13 to 15 mph, the tips are traveling at 120 mph. At maximum wind speeds, the blade tips are spinning at an estimated 180 mph.
