I learned something today. Great Horned Owls can look very evil at times. This particular guy/gal has been hanging around work for a week or so. Most of the time, he looked like he was sleeping. Both eyes closed. One eye closed, one eye at half mast. Rarely, both eyes open, but, not the big owl stare I see in photos. Regardless of the eye position, his head moved when I moved. How do they see through closed lids? Another thing, no ear protection and it's really noisy under a turbine inlet.
