I was on the top level of the boat, and was pleased to get the best view I could have of a frigate. I had the camera (also a bonus). Frigates have an odd characteristic when they are in their mating season. The males have a pouch which inflates like a red balloon under the beak. Unfortunately our trip was at the end of that period, and I only saw a few hints of those red pouches. This one was not among those. Given the movement of the boat and the flight of the bird, I was pleased I got this one as clearly as I did.
