Bird Flocking Behavior and Theories

The video explores why different bird species use various flocking patterns, such as the V-formation or clumping. 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 flock for protection against predators, as explained by the Selfish Herd theory. The video concludes with a promotion for the SciShow podcast.

What is the typical shape of a bird flock that includes a leader and trailing birds?

• Line

• Circle

• Square

• V-shape

Why do larger birds like geese prefer flying in a V-formation?

• To fly faster

• To confuse predators

• To conserve energy and avoid collisions

• To look more intimidating

How much energy can birds save by flying in a V-formation?

• 5%

• 10%

• 15%

• 20%

What is a key reason smaller birds do not fly in a V-formation?

• Their wing flapping creates inconsistent vortices

• They prefer flying alone

• They are too fast

• They don't migrate

What happens to the vortices created by small birds' wing flapping?

• They are too weak to be useful

• They help in faster flight

• They form a perfect V-shape

• They create a strong updraft

What is the primary reason small birds fly in groups?

• To conserve energy

• For protection from predators

• To travel faster

• To find food

Who proposed the Selfish Herd theory?

• Charles Darwin

• William David Hamilton

• Alfred Wallace

• John Maynard Smith

What does the Selfish Herd theory suggest?

• Animals prefer to be alone

• Risk is reduced by placing others between oneself and a predator

• Predators avoid large groups

• Animals are always selfish

What is a common survival strategy among animals like birds, fish, and insects?

• Hiding underground

• Forming groups or flocks

• Flying solo

• Changing colors
