Studies have been done on relict populations in isolated mountain and valley habitats in western North America, where the basin and range topography creates areas that are insular in nature, such as forested mountains surrounded by inhospitable desert, called sky islands.
How many species of birds are in danger of extinction?
Other areas, such as Guam, have also been hit hard; Guam has lost over 60% of its native bird taxa in the last 30 years, many of them due to the introduced brown tree snake . Currently there are approximately 10,000 living species of birds, with an estimated 1,200 considered to be under threat of extinction.
