The 2018 State of the World’s Birds report, which provides a comprehensive look at the health of bird populations globally, has found that the extinction crisis has spread so far that even some well-known species are now in danger.
Overall, it shows that 40 percent of the world’s 11,000 bird species are in decline, and one in eight bird species is threatened with global extinction.
The threats driving the avian extinction crisis are many and varied, but invariably of humanity’s making.
One of the greatest of those threats, according to the report, is agriculture. The expansion of agriculture, as well as its intensification, impacts 1,091 (74 percent) of globally threatened birds. One example of how agriculture is negatively impacting birds can be found in the neurotoxic insecticides known as neonicotinoids or ‘neonics’.
In addition to these worrying trends, though, the report also contains numerous findings that encourage hope. It finds that at least 25 bird species would have gone extinct in recent decades were it not for conservation interventions. The report outlines actions and changes that need to occur for birds and biodiversity to be better conserved. This includes restoration of habitats key to birds, eradicating and controlling invasive species, and targeting the most vulnerable bird species in order to protect them.
