The Galapagos Islands are known for their giant tortoises and finches. Usually, these species are related to the book “On the Origin of Species” by Charles Darwin, which was published in 1859. However, many years earlier during the months of September and October 1835, Charles Darwin visited the Galapagos archipelago aboard the research vessel HMS Beagle; where he was not studying Darwin’s finches, but mockingbirds and four subspecies:
- Cucuve Hood
- San-Cristobal Cucuve
- Cucuve de Galapagos
- Cucuve Charles
Cucuves helped young Charles to develop the idea of adaptation of species to their environment. He compared the cucuves collected from different islands and found that all of them had descended from common ancestors.
In four different islands they had adapted to the different conditions of life and develop independently. This is demonstrated by the different lengths of the beak and plumage.
Hyperactive Cucuves are easy to observe in Puerto Ayora and throughout Santa Cruz Island. They alway try to curiously approach to people. For example, in Tortuga Bay, they try to catch crumbs; although it is not advisable to feed the birds, since nature offers them everything they need for food.
