ENDEMIC BIRD AREAS OF THE WORLD Priorities For Biodiversity Conservation Birdlife International, 1998

Among the various animal and plant groups, birds can serve as effective indicators to identify areas important for overall biodiversity conservation. Birds are much easier to observe and census than most other groups, and are much better known taxonomically. In a recent publication, BirdLife International (formerly known as the International Council for Bird Preservation) analyzed the distributions of birds on a global scale and found that centers of endemism for birds corresponded well with those for other groups that were more difficult to study, including mammals, reptiles, amphibians, and butterflies.

  • 1)

    Over 25% of all birds (2,561 species) have restricted ranges, being confined to areas of less than 50,000 Km2

  • 2)

    These small areas overlap to form Endemic Bird Areas (EBAs), such that the majority of restricted-range species (93% of them) are encomposed by 218 EBAs.

  • 3)

    EBAs are found around the world, but most (77%) of them are located in the tropics and subtropics.
