Half of world's birds in decline – report

ALMOST half of all bird species are in decline globally and one in eight are threatened with extinction, according to a major new report warning that human actions are driving more species to the brink and nature is "in trouble."

The four-yearly State of the World's Birds report, which provides a snapshot of the plight of species globally and more broadly a barometer for biodiversity, comes as the United Nations steers an international process to protect nature.
