A special place especially for nesting seabirds. Apart from blue-footed and Nazca boobies nesting here, it is the only place in the world where waved albatross nest and breed. It is a dry, low island with a famous and healthy population of saddle-backed tortoises.
There are a great number of other endemic organisms, sufficiently different enough from the other islands like the Hood mocking bird and the lava lizards with their distinct red heads. The marine iguanas also have huge patches of red and often bright green, detracting from the black appearance of other islands.
The northern half of the island is cliff, making it perfect for seabirds and albatross launching pads.
