Daphne Major

Daphne Major is an island just north of Santa Cruz Island and just west of the Baltra Airport in the archipelago Colon, commonly known as the Galapagos Islands. It consists of a tuff crater, devoid of trees, whose rim rises 120 metres above the sea.

Though easily accessible to most visitors to the Galapagos, the national park has highly restricted visits to this island and it is primarily used as a scientific research spot. An intensive study of Darwin's Finches was conducted here by biologists Peter and Rosemary Grant over a period of 20 years. They examined the behaviour and life cycles of finches, with the results strongly supporting Darwin's theory of evolution their efforts were documented in the Pulizer Prize winning book The Beak of the Finch.

Daphne is home to a variety of other birds including Galapagos Martins, Blue-footed Booby, Masked Booby, Short-eared Owls, Red-billed Tropicbirds and Magnificent Frigatebirds.
