Africa’s endangered species
JULY 10, 2012
More than 150 bird species are known to have become extinct over the past 500 years, and many more are estimated to have been driven to extinction before they became known to science. The bulk of the recent bird extinctions has been on islands, where species are more susceptible to extermination due to smaller ranges, lower population sizes and a lack of adaptation for coping with introduced predators. The Northern Bald Ibis is listed as Critically Endangered.
