One-in-five migratory species facing extinction

The migratory hawksbill sea turtle is one of many marine animals, from sharks to sturgeons, threatened with extinction.

More than a fifth of migratory species under international protection are threatened with extinction, including nearly all nomadic fish, according to the first UN expert assessment.

From humpback whales to Dalmatian pelicans, each year, billions of animals journey with the seasons over oceans, on land and in the skies. But a new report by the Convention on the Conservation of Migratory Species of Wild Animals (CMS) has found that many migratory species are at risk of disappearing, threatened by human pollution, the spread of invasive species, and the climate crisis.
