It was a masked booby, a male, at Prince Philip's steps. On the ground and very proud of its acquisition, he had a frigate chick. The little one probably fell from his nest, which was not too far off the ground. When we got there, the mother frigate was also there trying to feed its young one, but the masked booby didn't let her approach the baby. It is very hard for frigates to land on the ground, so we saw the female flying around many times without any success.
Why did this happen? We don't have any idea. It might be that the male booby wasn't successful breeding this year, so he released his energy in a different way. We don't have the answers, and this just proves us how little we know about animal behavior and how much more we have to learn about nature and from nature. We will keep you informed about this bizarre case of the "Mad Masked Booby" kidnaping a frigate chick.
