A few years back late season goose , ice up everywhere but the river mouths. We had a flock of geese come in and proceeded to knock a few down. One bird was hit, but not real hard. It flew out over the lake struggling to stay up until we lost sight. I go out to pick up the birds and see two birds coming in hard and fast.....the wounded goose with a bald eagle on its butt looking to make breakfast. The goose hit the ice full speed, flopping and slid right up into the brush. That eagle hung around a bit, but we got the goose. That eagle flew like a fighter jet and had no qualms about trying to take a full grown greater Canada goose. Awesome birds
