Why are great animal migrations collapsing? DW 02/12/2024
Briefly

For centuries, the disappearance of birds during winter was a great mystery to Europeans. Some thought they hibernated underwater, or that they transformed into other species, or even went to moon. But by the 1800s, evidence of remarkable animal migrations started to emerge.
It's not just birds. Species of fish, mammals, insects and reptiles all undertake long-distance expeditions. The European eel can travel about 10,000 km over two years to reach its breeding grounds near the Bahamas. Gray whales summer in the cold northern Pacific before traveling to the coasts of California and Mexico. And herds of over one million wildebeest migrate hundreds of kilometers during the dry season in search of water in the Serengeti of Kenya and Tanzania.
