The Galápagos hawk is the apex predator on the Galápagos Islands — meaning it is at the top of the food chain and has no natural predators. Even so, it is an endangered species and there are only about 150 mating pairs left in existence. This has to do with human disturbance to their natural habitat, a dwindling food supply, and predation by humans. All that being said, we saw quite a few of them, including this guy that we ran into on the island of Rábida. We were on a hike and he seemed very intrigued by us, following us for quite some time, landing next to us and then turning his head from side to side while he looked from face to face.
