Up to 900 tropical bird species could 'go extinct'


Up to 900 species of tropical land birds around the world could become extinct by 2100, researchers say.
The finding is modelled on the effects of a 3.5C Earth surface temperature rise, a Biological Conservation Journal paper shows.
Species may struggle to adapt to habitat loss and extreme weather events, author Cagan Sekercioglu says.
Mountain, coastal, restricted-range, and species unable to get to higher elevations could be the worst affected.
Depending on future habitat loss, each degree of surface warming could affect between 100-500 species, says Mr Sekercioglu, assistant professor of biology at the University of Utah.
