Every visitor to the Galápagos Islands must be accompanied by a guide certified by Galápagos National Park. To qualify, a candidate must be Ecuadorian, pass a rigid study program and then attend continuing education. Only about 400 people meet these qualifications. Level three guides have years of experience, a master’s degree, an area of specialty and speak at least two languages. All of this is designed to optimize the tourist experience while helping to protect the fragile habitat. This naturalist at Darwin Bay Beach is describing the species of birds flying overhead.
