Frigate birds are thieves -- they steal food from other birds, including their own species. Yesterday Len caught this photo of one frigate bird chasing another that had just caught a fish. A moment later I think they both lost the fish. Greedy, greedy!
We also watched a huge feeding frenzy including boobies swooping down into the water and dolphins and dolphin-sized tuna swimming on the surface, evidently hunting in a huge school, or baitball, of small fish. You can see a tuna (towards the left) jumping out of the water among all the boobies.
