The world's migratory species are under threat across the planet with their global risk of extinction increasing, a landmark UN report released Monday has warned.
Until now there has been no comprehensive data on the conservation status or population trends of the billions of animals that make yearly migratory journeys across the world's lands, seas and skies.
These species often rely on very specialised sites to feed and mate. Their journeys can cross international borders and even continents.
Iconic species that make some of the most extraordinary journeys across the planet include the monarch butterfly, the humpback whale and the loggerhead turtle.
The first-ever State of the World’s Migratory Species report – which focuses on the 1,189 species covered by the UN Convention on the Conservation of Migratory Species of Wild Animals (CMS) – offers compelling evidence of the dangers they face.
It found that one in five species is threatened with extinction, and 44 percent are seeing their populations decline.
'Wake up call'
Humans are to blame for the threat to species by destroying or breaking up habitats, hunting, and polluting areas with plastics, chemicals, light and noise.
Over the past three decades, 70 species have become more endangered, including the steppe eagle, Egyptian vulture and the wild camel.
