I once saw a Bald Eagle swoop down about 20 feet ahead of my car, coming in from the right, capturing whatever was in the road, and flying up towards the left. It was over in a matter of seconds. Majestic is one word I thought of to describe this bird. He/she was also huge. I had no idea how big they were.
The Peregrine Falcon is the fastest bird on the planet. The American Kestrel is the smallest bird of prey in our country. If I remember right they are smaller than the blue jay. All of them can see for miles, and whether they look fierce or not so much, they are all beautiful. Here are a few examples.
