My wife watches the eagle cams every year during hatching season.
Good chance that eagle was heading to the nest with that bass.
When my wife started watching the eagles I warned her of 2 things...data shows that only around 60% of hatchlings survive.
And that the parents are totally indiscriminate with what they catch, kill and bring to the nest for the babies....and that can include domestic animals.
I live on a fairly large lake in Central Florida and there are numerous ospreys and bald eagles that have nests near the lake. This eagle was flying fairly low and I was in my back yard near the lake, but with an oak tree between me and the lake. The eagle flew over the tree and there I was. I probably startled it and it dropped the bass bomb on me.
