We had an interesting eagle encounter while fishing on the lower Yellowstone River, below Livingston, MT several years ago.
A friend of mine hooked and released a sizeable brown trout (18-19") while we were anchored in my drift boat on the upper section of a long flat pool - kind of like the Broad Water pool on Penns, Luke, only larger and longer. The trout had been hooked deeply, and we weren't sure he would make it when we released it, but he swam off, heading down river.
As we remained anchored for for several minutes, we looked downriver toward the tail of the pool, maybe a half mile distance, and saw a bald eagle swoop down and grab what was surely the trout we had just released from near the surface of the water. He struggled a bit with that trout to get airborne, but once he gained elevation, he flew directly back upriver toward us, dropped the trout in the grass on the river's edge directly across the river from us, and perched above the trout in a partially dead cottonwood tree.
As if that wasn't enough, as we sat anchored watching that bald eagle, over the course of the next few minutes, 4 more eagles (including a golden eagle) flew in, and landed. Three bald eagles landed in the cottonwood above the trout in the grass, and the golden eagle and the other bald eagle perched on a high rock cliff on the opposite side of the river. We theorized that these eagles had been soaring high overhead, out of our vision, but had seen the trout and had come to fight over what would be a good meal. I'm sure they all knew the trout was laying in the grass, but none of the eagles would go down to get him while we were there.
I spend the entire summer on the Yellowstone River but that is the most eagles I have ever seen together at one time, although we see eagles and osprey practically every day. I understand that that particular area has the largest concentration of golden eagles in the country.
