I have only been able to photograph a few owls. The Great Horned and Barred were captive, the Snowy not so much. It had stayed in one spot for hours (I only was there for the last 45 minutes, but others had been there for 5 or 6 hours, waiting) and then when it took off I managed to get only 2 frames before it was gone.
Thanks Click. His name 8s Pete and it is crop from a shot of my middle daughter holding him. She and my youngest spent several of their mid-teen years working with raptors at a nearby farm. I shot it from just a few feet away with my old 30D. Credit the 70-200/2.8 L IS II for the sharpness, it is a wonderful piece of glass.
