The State of the World’s Birds, an annual review of environmental resources was recently published.
Key Findings of the Study:
- 48% of the extant bird species are undergoing population decline.
- 5% of 10,994 recognised extant species are currently threatened with extinction of which:
- 9% are Near Threatened
- 7% are Vulnerable
- 4% are Endangered
- 2% are Critically Endangered
- Alongside tropical forests, natural grasslands emerge as a habitat that is particularly threatened.
- Threat of natural grasslands has been particularly worrying for North America, Europe and India.
- It highlights the need for conservation as birds are sensitive indicators of environmental health.
- The degradation and loss of natural habitats as well as direct overexploitation of many species are the key threats to avian biodiversity.
- The use of 37% of the surviving bird species as common or exotic pets and 14% as food are examples of direct overexploitation.
