In fact, it was once said that you could walk across the Galapagos Islands without touching the ground, by walking on the backs of tortoises. But now, due to the combined efforts of introduced species, such as the goat and the black rat, and the old pirates, sailors, and whalers, the Galapagos giant tortoise is now endangered. There are also many species of birds in the Galapagos Islands, among which are boobies and frigatebirds. Of the six species of booby, three live in the Galapagos. A boobie's body is shaped like a torpedo, so they can move quickly through water and air.
Boobies eat fish, and so do frigatebirds.
But unlike boobies, frigatebirds' feathers aren't waterproof, so they can't land on or dive into the water. So instead of catching their fish the honest way, frigatebirds go around pestering other seabirds until the other bird regurgitates the fish that it has caught. Then the agile frigatebird swoops under other bird and catches the regurgitation in its mouth. Roughly 10,000 people live in the three towns on the Galapagos Islands. The largest town is Porta Yora, which is located on Isla Santa Cruz.
