Human actions and the climate crisis are putting 49% of the world's bird species in decline

"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.

The previous State of the World’s Birds report, released in 2018, found 40% of bird species worldwide in decline.

Wildfires feature more prominently in this report than previous editions, having increased and ravaged previously unaffected habitats. The succession of heatwaves, droughts and floods in recent years will lead to widespread species extinctions if they continue, researchers warn, highlighting the importance of addressing the nature and climate crises at the same time.

Growing evidence links the health of bird populations to human health. Covid-19 is a warning of what could happen if we continue to destroy the natural world, with 70% of zoonotic diseases originating in wildlife. A highly pathogenic variant of avian flu – the result of intensive farming – has driven rapid declines in some bird populations this year. More than 300 outbreaks have been reported in UK seabird colonies."
