Why Don't Birds on Power Lines Get Zapped?

The video explains why birds can perch on power lines without harm, focusing on electrical currents and potential. It highlights the dangers of electricity, how circuits work, and why larger birds like raptors are at risk of electrocution. Utility companies are implementing safer designs to protect these birds. The video emphasizes the importance of understanding electricity's potential dangers.

Why don't birds get electrocuted when they sit on a single power line?

• Because they are immune to electricity.

• Because power lines are insulated like appliance cords.

• Because they have special insulating feathers.

• Because both feet are on the same wire, preventing a potential difference.

What happens when a bird touches two wires with different potentials?

• The bird's feathers protect it from the current.

• The bird becomes a conductor and gets electrocuted.

• The bird flies away unharmed.

• The bird absorbs the electricity safely.

Which type of birds are most at risk of electrocution from power lines?

• Small songbirds like sparrows.

• No birds are at risk.

• Waterfowl like ducks.

• Larger raptors like eagles and hawks.

What is one method utility companies use to protect birds from electrocution?

• Installing birdhouses on power poles.

• Using ultrasonic bird deterrents.

• Painting power lines in bright colors.

• Designing power poles that discourage perching.

What is the primary reason electricity can be dangerous to both humans and birds?

• It can complete a circuit through the body.

• It can create loud noises.

• It can attract predators.

• It can cause fires.
