North of Santa Cruz Daphne Major is a small volcanic island, a sparsely vegetated tuff cone with an area of less than half a square kilometer. It is extremely difficult to land on and can only be visited by special permit. Most ships only cruise past it or might even circumnavigate the island. Devoid of larger trees, the rim of the volcano’s cone rises to 120 meters. Cactus bushes, small trees and herbs provide food for several finch species –and a ground-breaking study in evolution over a forty year time span showed how food resource availability has led to evolutionary changes in finches. Apart from these small land birds, Red-billed Tropicbirds, Magnificent Frigatebirds and Nazca and Blue-footed Boobies also nest on Daphne Major and can often be seen soaring.
