Bald Eagles key in on waterfowl in the late fall just before the ice takes hold and the open water is gone in Grand Teton National Park. When I arrived at the lake with. I first noticed the group of Red Heads. I looked around a bit more, and I noticed this eagle perched low and just out of sight along the river. I knew it was a matter of time before it made an attempt for the ducks. An hour or so passed and the eagle launched into the air. Flying low and using the topography to its advantage, the eagle had the element of surprise. Even still, it wasn't enough, and after five or six unsuccessful dives the eagle gave up for the afternoon. Nonetheless, it was an adrenaline rush watching the whole event unfold.
