Nearly half of the world's migratory species are in decline, according to a new United Nations report released Monday.

Many songbirds, sea turtles, whales, sharks and other migratory animals move to different environments with changing seasons and are imperiled by habitat loss, illegal hunting and fishing, pollution and climate change.

About 44% of migratory species worldwide are declining in population, the report found. More than a fifth of the nearly 1,200 species monitored by the UN are threatened with extinction.

“These are species that move around the globe. They move to feed and breed and also need stopover sites along the way,” said Kelly Malsch, lead author of the report released at a UN wildlife conference in Samarkand, Uzbekistan.

Habitat loss or other threats at any point in their journey can lead to dwindling populations.

“Migration is essential for some species. If you cut the migration, you’re going to kill the species,” said Duke University ecologist Stuart Pimm, who was not involved in the report.

The report relied on existing data, including information from the International Union for Conservation of Nature's Red List, which tracks whether a species is endangered.

Participants of the UN meeting plan to evaluate proposals for conservation measures and also whether to formally list several new species of concern.

“One country alone cannot save any of these species,” said Susan Lieberman, vice president for international policy at the nonprofit Wildlife Conservation Society.

At the meeting, eight governments from South America are expected to jointly propose adding two species of declining Amazon catfish to the UN treaty's list of migratory species of concern, she said.

The Amazon River basin is world’s largest freshwater system. “If the Amazon is intact, the catfish will thrive — it's about protecting the habitat,” Lieberman said.

In 2022, governments pledged to protect 30% of the planet's land and water resources for conservation at the UN Biodiversity Conference in Montreal, Canada.

Tests results released Friday showed the water quality in the River Seine was slightly below the standards needed to authorize swimming — just as the Paris Olympics start.

Heavy rain during the opening ceremony revived concerns over whether the long-polluted waterway will be clean enough to host swimming competitions, since water quality is deeply linked with the weather in the French capital.

Paris Mayor Anne Hidalgo took a highly publicized dip last week in a bid to ease fears. The Seine will be used for marathon swimming and triathlon.

Daily water quality tests measure levels of fecal bacteria known as E. coli.

Tests by monitoring group Eau de Paris show that at the Bras Marie, E. coli levels were then above the safe limit of 900 colony-forming units per 100 milliliters determined by European rules on June 17, when the mayor took a dip.

The site reached a value of 985 on the day the mayor swam with Paris 2024 chief Tony Estanguet and the top government official for the Paris region, Marc Guillaume, joined her, along with swimmers from local swimming clubs.

At two other measuring points further downstream, the results were below the threshold.

The statement by Paris City Hall and the prefecture of the Paris region noted that water quality last week was in line with European rules six days out of seven on the site which is to host the Olympic swimming competitions.

It noted that "the flow of the Seine is highly unstable due to regular rainfall episodes and remains more than twice the usual flow in summer," explaining fluctuating test results.

Swimming in the Seine has been banned for over a century. Since 2015, organizers have invested $1.5 billion to prepare the Seine for the Olympics and to ensure Parisians have a cleaner river after the Games. The plan included constructing a giant underground water storage basin in central Paris, renovating sewer infrastructure, and upgrading wastewater treatment plants.
