Where are all the birds?
12 percent of existing species — about 1,250 — are threatened with extinction by 2100.

Up until now, scientists had documented the extinction of about 130 bird species since the year 1500. But the study’s authors — from Stanford University, Duke University and the Missouri Botanical Garden in St. Louis — say the more accurate estimate is about 500 extinctions out of more than 10,000 known bird species. That would be about one extinction per year over the last 500 years.

Bird Extinction Estimates May Be Too Low
