This was filmed at Torrey Pines several years ago. I was looking at some of the sequence shots I took Friday of the young peregrine falcon, not even a week in the air, divebombing the pelicans. Amazing really. That this behavior is so innate. Bird is a month old. Not much bigger than a sparrow. Taking on a whole flock.
It was incredible. Several pelicans went upside down to evade the invader. One almost completely lost it. Ultimately everyone regained their balance and flew away.
