Why Don't All Birds Fly in V Shapes?

The video explores why different bird species use various flight formations, such as the V shape or clumps. Larger birds like geese benefit from the V formation by conserving energy and maintaining visual contact. This is due to the vortices created by their wing flaps. Smaller birds, however, do not generate consistent vortices and often fly in clusters for protection against predators, as explained by the selfish herd theory. The video highlights the role of bird size and wing structure in determining flight patterns.

What is one primary reason birds like geese fly in a V formation?

• To confuse predators

• To conserve energy

• To find food

• To navigate better

Why do larger birds benefit from flying in a V formation?

• They can see predators more easily

• They can communicate better

• Their wing structure allows them to create useful vortices

• They can fly faster

Why don't smaller birds typically fly in V formations?

• Their wing flapping creates inconsistent vortices

• They prefer to fly alone

• They have better eyesight

• They are too light to maintain formation

What is the 'selfish herd' theory?

• Animals group together to share food

• Animals group together to reduce individual risk from predators

• Animals group together to migrate more efficiently

• Animals group together to find mates

How does the 'selfish herd' theory apply to bird flocks?

• Birds scatter to avoid being caught

• Birds fly in a line to conserve energy

• Birds stay close to reduce individual risk from predators

• Birds fly in a V to confuse predators
