Thanks for sharing. Very cool. Once, there were three sparrow hawks (American Kestrals) trapped in my brother-in-law's shop/building. The mother was nesting in one of the vents and when the chicks were ready for flight, they found a way to come in rather then going out. Pretty exciting having them zipping overhead inside the building which was only about 3500 sq ft. I was able to capture them with a pair of welding gloves. They were very beautiful creatures and though their talons were small, they were incredibly sharp.
