Greg Estes

Greg has served as a licensed naturalist guide in the Galápagos Islands since 1982. After graduating with a degree in biology from the University of London, he led the Cambridge Darwin Centenary Galápagos Expedition of 1982, which studied the feeding ecology of marine iguanas. He has extensively researched Charles Darwin and with his wife, Thalia Grant, published the results from their expedition to retrace Darwin’s footsteps through the Galápagos in Notes and Records of the Royal Society of London (2000). He has recently published a book titled, Darwin in Galápagos, Footsteps to a New World. Greg has participated in several other research projects, including studies of sperm whales and the dark-rumped petrel, a seabird endangered due to the presence of introduced animals. Maker of the Galápagos video Galapagos Suited for Survival, Greg has been active in saving the Galápagos marine environment, which is threatened by the impact of illegal fishing. Other projects include filming the evacuation of giant tortoises that were threatened by the lava flow from the eruption of Isabela’s Cerro Azul volcano and working as a consultant to the BBC and National Geographic on their recent award winning series. Greg has traveled extensively throughout Europe, North America, Central and South America, northern Africa, the Falkland Islands, South Georgia, and Antarctica.
