The fauna of Barbados is less diverse than that of the other Antilles. Human activities are responsible for the change in the composition of the fauna, in particular, the replacement of native species. Species that are able to adapt to human presence have survived.
Origin of Barbadian Fauna
The island of
Barbados
Barbados is an island country in the Lesser Antilles of the West Indies, in the Caribbean region of the Americas, and the most easterly of the Caribbean Islands. It occupies an area of and has a population of about 287,000 (2019 estimate) ...

Avian
Avian may refer to:
*Birds or Aves, winged animals
*Avian (given name) (russian: Авиа́н, link=no), a male forename
Aviation
*Avro Avian, a series of light aircraft made by Avro in the 1920s and 1930s
*Avian Limited, a hang glider manufacture ...
colonization has therefore occurred recently relative to the geological age of the island, accounting in part for the lack of
endemic species
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsew ...
relative to neighboring islands.
Species capable of crossing the sea barrier by flight enjoyed a comparative advantage, helping to explain why avian species are more numerous than other animal groups, such as mammals. In addition to the natural colonization of the island by animals, humans have contributed to the faunal composition of the island through species introductions (intentional and accidental).
