Humans have had a profound effect on many bird species. Over one hundred species have gone extinct in historical times, although the most dramatic human-caused extinctions occurred in the Pacific Ocean as humans colonised the islands of Melanesia, Polynesia and Micronesia, during which an estimated 750–1,800 species of birds became extinct. [1]
About 216 species of birds have become extinct since 1500, [1] with increasing extinction rates due to human-caused influences such as habitat loss, the introduction of invasive species, and climate change. [2] [3] Currently there are approximately 10,000 living species of birds, with over 1,480 at risk of extinction and 223 critically ...
