The first UN expert assessment has shown that more than a fifth of migratory species under international protection are threatened with extinction, including nearly all nomadic fish.
From humpback whales to Dalmatian pelicans, each year, billions of animals journey with the seasons over oceans, on land and in the skies. However, 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.
The assessment of migratory animals that are under protection from the treaty found that 22% of the 1,189 CMS-listed species are threatened with extinction and nearly half, 44%, are showing population declines, with many under unsustainable pressure from habitat loss and overexploitation. As much as 97% of sharks, rays and sturgeons on the list are facing a high risk of extinction, with populations declining by 90% since the 1970s.
According to the assessment, Wildlife can travel enormous distances while migrating, culminating in some of nature’s most dramatic journeys, such as a million wildebeest travelling from the Serengeti in Tanzania to the Maasai Mara in Kenya, and Pacific salmon returning upriver to breed across the west coast of the US.

Gorillas and nearly half of all turtles covered by the convention are in danger of disappearing, according to the analysis, while those experiencing declines include bar-tailed godwits, which fly more than 8,000 miles nonstop between Alaska and Australia, the straw-coloured fruit bat, which undertakes the largest mammal migration, across Africa, and the critically endangered European eel.
The report comes as governments gather for a summit in Samarkand, Uzbekistan, to discuss how to better protect the world’s migratory species. Executive secretary Amy Fraenkel told the Guardian that the trend toward increased extinction risk was a “huge cause for alarm”, but there was also much that governments could do about the declines.
“The reason why species are covered by the convention is because they are in trouble – it is not surprising to find that some of them are endangered. The problem is the trend: 44% of listed species are in decline and that increasing extinction risk is something that applies globally to migratory species,” Fraenkel said.
