We had the good fortune of visiting GTNP and spending the evening at Cattleman's Crossing. We were very fortunate to observe many things including a black bear, merganzer, bald eagle, and spotted sandpipers. The merganzer had caught a rather large fish and was quickly trying to eat it. All of a sudden an osprey swooped down and tried to take the fish away but was unsuccessful. A minute or two later the osprey was at it again and this time with success. What an amazing sight to witness.
