Las aves rapaces enfrentan declinación global
August 31, 2021 - De las 557 especies de aves de presa del mundo, 166 (30%) están en creciente riesgo de extinción debido a actividades humanas, según hallazgos de nuevo análisis.
Despite a few high-profile conservation success stories – like the dramatic comeback of bald eagle populations in North America –new analysis of data from the International Union for the Conservation of Nature and BirdLife International found that 30% of raptor species are considered near threatened, vulnerable or endangered or critically endangered.
Eighteen species are critically endangered, including the Philippine eagle, the hooded vulture and the Siau scops owl, the researchers found.
The population of the Philippine eagle – the world’s largest eagle – is in rapid decline due to deforestation. the Harpy eagle – the largest eagle in the Americas – is classified as Near Threatened for the same reason.
Some vulture species in Asia and Africa have declined by 95% through habitat loss and poisoning by feeding on carcasses of livestock treated with the anti-inflammatory drug diclofenac.
Of 4,200 sites identified by conservation groups as critical for raptor species globally, most “are unprotected or only partly covered by protected areas,” said Stuart Butchart, chief scientist at BirdLife International in the United Kingdom.
