No joke, these birds flew along side our ship for an entire day. I’ve never seen anything like it. They would start at the ship’s stern, then slowly work their way up to the bow. The entire time, flying only a few inches above the water as they hunted small fish. They are common to the Pacific Ocean along the shipping routes near Panama. After flying with us for 24 hours, they were gone. Apparently they joined a ship headed back south.
