Due to the lack of natural predators, the wildlife in the Galápagos is extremely tame and has no instinctive fear. [1] The Galápagos Islands are home to a remarkable number of endemic species. The stark rocky islands (many with few plants) made it necessary for many species to adapt to survive and by doing so evolved into new species.
For example, 50% of endemic bird areas are found on islands. [2] Endemism is often the result of adaptive radiation. [1] Adaptive radiation is when a single species colonizes an area and rapidly diversifies to fill all of the available niches. A common example is the assemblage of finch species documented by Charles Darwin in the Galapagos ...

The islands are home to 29 native species of land birds, 24 of which are endemic. Endemic species include the Galapagos hawk (Buteo galapagoensis), Galapagos dove (Zenaida galapagoensis), Galapagos rail (Laterallus spilonota), Galápagos martin (Progne modesta), and four species of mockingbirds from genus Nesomimus.

This is a list of animals that live in the Galápagos Islands.The fauna of the Galápagos Islands include a total of 9,000 confirmed species. Of them, none have been introduced by humans, and seventeen are endemic.
Coastal lakes, moist soil and areas where freshwater and seawater mix contain unique species still to be studied. Cold, hot and warm marine currents come together here, generating a wide diversity of animal life: from small coloured fish to large mammals: [3] marine iguanas, Galapagos land iguanas, galapagos crabs, Galápagos sea lion, Sharks, Blue footed boobie, swallow-tailed gulls, ducks ...
The Galapagos albatross is one of those species where the males and females dance together, however, unlike the flamingo group dance, this dance is a unique courtship ritual between the two mates.
Many found the early examples unconvincing and suggested it to be a rare phenomenon. Criticisms with earlier studies included the lack of rigor in statistical analyses and the use of poorly rationalized characters. [5] [8] Additionally, theory seemed to indicate that the conditions that allowed character displacement to occur were limited. [8]
