Aves migratorias

The video explains how migratory birds travel thousands of kilometers between snowy and sunny regions during winter and summer. These migrations are guided by the Earth's magnetic field, which birds can detect and possibly see. The magnetic field is strongest near the poles and weakest away from them, helping birds navigate. By understanding the field's strength, birds can determine their migration routes, moving to warmer areas in winter and cooler ones in summer.

What is the primary reason migratory birds travel long distances during different seasons?

• To explore new territories

• To move between snowy and sunny places

• To escape predators

• To find new habitats

How does the Earth behave in terms of its magnetic properties?

• As if it has a magnet from north to south

• As if it has no magnetic properties

• As if it has a magnet from top to bottom

• As if it has a magnet from east to west

What do scientists believe about birds' ability to detect the Earth's magnetic field?

• Birds can see the magnetic field

• Birds can taste the magnetic field

• Birds can smell the magnetic field

• Birds can hear the magnetic field

How do migratory birds use the Earth's magnetic field during winter?

• They travel to a stronger part of the field

• They travel to a weaker part of the field

• They travel to the equator

• They travel to the poles

During summer, where do migratory birds fly in relation to the Earth's magnetic field?

• To a weaker part of the field

• To the equator

• To the southern hemisphere

• To a stronger part of the field
