This reminds me of the flying squirrels we have around our cottage. What fun to sit below the trees and have them swish in to the feeder just inches above you head.
However, man, those guys really have to know the winds in that location. Seems pretty close to some of the cliff walls. One good gust of wind, no room for error.
What happens when an error is made... (nothing graphic, but it tells the story quite well)
