One of my all-time favorite stories of this happening is from at least 10 years ago and probably a little more. I was fishing a high mountain lake in Arizona's White Mountains in the hopes of catching my first apache trout. The fishing was slow to the point that I started to wonder if there were even any fish in the lake.
Right about that time, a large bald eagle came soaring overhead. Soon the bird spotted a large trout. I watched in awe as it dove and snatched what looked to be a 24" trout, give or take a couple of inches. I never did catch a fish on that particular fishing trip, or at least not on that lake. That much I clearly remember, almost as clearly as I can still see the bird struggling to fly away with its heavy catch.
I've seen herons take fish on many occasions as well. In fact, When they are around, they generally seem to be doing better than I am on the catching scene.
Have you ever been humbled by a master fisherman?
