Pretty crazy stuff there. I do a good bit of falconry hunting photography and have never seen one go after something that much larger than itself. Amazing too the falcon didn't get hurt by the goose with all the wing flailing that went on. Interesting to read this bird eventually met its match with a eagle. Many falcons meet their demise in areas inhabited by Golden Eagles. The eagles watch from afar and after the falcon makes its kill and starts to feed...the eagle comes in for both.
