Daphne Major is a rather large tuff cone somewhat eroded by the sea. It is a very fragile visitor site and requires a special permit. Nazca boobies, red-billed tropicbirds, and blue-footed boobies can be found nesting here. Daphne Major is the primary site of Peter and Rosemary Grant’s iconic 40-year study of evolution in Darwin’s finches that demonstrates evolution occurring over short periods of time. Nearly all of the finches on the island are banded.
