Birds that Hibernate in Lakes!

The video explores historical and modern methods of understanding bird migration. Initially, people believed birds hibernated underwater or flew to the moon. The introduction of bird banding in the 1900s provided the first real insights into migration paths. Satellite and GPS tracking further advanced our knowledge, though they have limitations for small birds. Light-level geolocators, which use ancient navigation methods, have revealed detailed migration patterns, such as the great snipe's rapid journey and the Arctic tern's extensive travels.

How did researchers first start to track migratory birds in the early 1900s?
