Study identifies how pigeons navigate using magnetic fields

The video explains an experiment where pigeons were placed in a controlled environment with an adjustable magnetic field. Electrodes in their brains showed neuron activation when the magnetic field changed. This experiment demonstrated how pigeons use variations in the Earth's magnetic field, including direction, intensity, and polarity, to navigate long distances.

What was the purpose of placing pigeons in a black room with an adjustable magnetic field?

• To test their ability to find food in the dark

• To observe their reaction to light changes

• To study their response to sound variations

• To control the magnetic environment for the experiment

What did the electrodes in the pigeon's brains help scientists to observe?

• The pigeons' heart rate

• The pigeons' vocalizations

• The activation of neurons in response to magnetic field changes

• The pigeons' sleep patterns

How do pigeons use the Earth's magnetic field according to the experiment?

• To find food sources

• To identify predators

• To communicate with other pigeons

• To navigate long distances

Which aspects of the Earth's magnetic field do pigeons use for navigation?

• Wind speed and direction

• Temperature and humidity

• Direction, intensity, and polarity

• Sound and light

What was the main conclusion of the scientists from the experiment?

• Pigeons rely on visual cues for navigation

• Pigeons can only navigate short distances

• Pigeons use magnetic field changes to navigate

• Pigeons are unaffected by magnetic fields
