UN Report: Almost half of the world's moving species are decreasing.

Nearly half of the world's migratory species are in decline, according to a new United Nations report. Many migratory animals like songbirds, sea turtles, and whales face threats from habitat loss, illegal hunting, and climate change.

The report says about 44% of migratory species are seeing population declines. More than one fifth are at risk of extinction.

Kelly Malsch, the report's lead author, emphasizes the global nature of these species' movements. Threats at any point in their migration can severely impact their numbers.

The report bases its findings on data from sources like the International Union for Conservation of Nature's Red List. At a U.N. meeting, attendees will discuss new conservation measures and species to focus on.

Joint efforts among countries are crucial for the survival of migratory species. For example, South American governments are proposing to protect Amazon catfish due to the importance of preserving their habitat.
