Half of world’s bird species in decline as destruction of avian life intensifies

State of the World's Birds report warns human actions and climate crisis putting 49% in decline, with one in eight bird species under threat of extinction

Nearly half of the planet's bird species are in decline, according to a definitive report that paints the grimmest picture yet of the destruction of avian life.

The State of the World's Birds report, which is released every four years by BirdLife International, shows that the expansion and intensification of agriculture is putting pressure on 73% of species. Logging, invasive species, exploitation of natural resources and climate breakdown are the other main threats.
