During our visit to Genovesa Island, I started to realize something I believe is so true: anywhere that we travel, anywhere that we go, we always see some birds and, we admire their ability to survive under conditions that are inhospitable for other animals.
They are the last great "adventurers" on earth, and their free ranging-existence is especially alluring from the standpoint of man's own desire for freedom. But while humans have always possessed some knowledge of birds, it is only in the last few centuries that scientific methods have applied to them, and that a systematic understanding of birds has developed.
As distinctive marine habitats offer different kinds of food, there are degrees of specialization in the diets of sea birds. Piracy is the one related to frigatebirds, which were named for their habit of taking food on the wing. Like the infamous frigate ships, frigatebirds wait for an unsuspecting victim to return to its nest carrying food, then swoop after the meal with remarkable grace.
It is so funny to watch these birds starting their breeding cycle: the process involving the males inflating their gular sacs is an operation that demands skills and expertise in order to have a response from the females. We can consider this a legacy of courtship among seabirds.
