Jonathan Wood said he knew the Time magazine photo shoot with his 27-year-old bald eagle named "Uncle Sam" and GOP presidential front-runner and real-estate mogul Donald Trump was going to be very difficult. On Wednesday, Time released footage of the August cover shoot that included the eagle lunging at Trump, who flinched in terror. It also showed the eagle flipping Trump's hair while on his shoulder. Trump told Fox News Thursday he wasn't "really" scared of the majestic bird. Wood added that when the eagle tried to bite Trump, causing the candidate to lunge away in fear, he had forgotten to mention something very important. Uncle Sam, as bald eagles do, would claim any space it's set on as its territory. And he would try to defend it.
