One in eight bird species threatened with extinction, global study finds

News via the Guardian:

Report on the state of the world’s birds reveals a biodiversity crisis driven by intensive farming, with once-common species such as puffins and snowy owls now at risk.

One in eight bird species are threatened with global extinction, and once widespread creatures such as the puffin, snowy owl and turtle dove are plummeting towards oblivion, according to the definitive study of global bird populations.

The State of the World’s Birds, a five-year compendium of population data from the best-studied group of animals on the planet, reveals a biodiversity crisis driven by the expansion and intensification of agriculture.

In all, 74% of 1,469 globally threatened birds are affected primarily by farming. Logging, invasive species and hunting are the other main threats.

“Each time we undertake this assessment we see slightly more species at risk of extinction – the situation is deteriorating and the trends are intensifying,” said Tris Allinson, senior global science officer for BirdLife International, which produced the report. “The species at risk of extinction were once on mountaintops or remote islands, such as the pink pigeon in Mauritius. Now we’re seeing once widespread and familiar species – European turtle doves, Atlantic puffins and kittiwakes – under threat of global extinction.”
