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.

What was one of the early theories about where birds went during winter?

• They traveled underground.

• They stayed in their nests.

• They migrated to the Arctic.

• They flew to the moon.

What was the first method used to track bird migration paths?

• GPS recorders

• Bird banding with metal rings

• Satellite transmitters

• Light-level geolocators

What is a major limitation of using satellite transmitters for tracking small birds?

• They are too expensive.

• They require frequent maintenance.

• They provide inaccurate data.

• They are too heavy for small birds.

How do light-level geolocators help in tracking bird migration?

• By using the length of day and time of noon

• By broadcasting signals to satellites

• By recording the bird's heartbeat

• By attaching to the bird's wings

Which bird is known for having the longest migration route?

• Bald eagle

• Arctic tern

• Great snipe

• Bar-tailed godwit
