Why is the arctic tern known as a champion migrator?

Why do some birds fly in flocks?
a) There is safety in numbers.
b) There is no known reason.
c) They are communal or 'community-oriented' birds.
d) They are less likely to get lost in a group.

What is the benefit of flying in formation during migration?
a) It allows all the birds to conserve energy by sharing the duty of breaking the wind current.
b) It enables other birds migrating in the same direction to know which way to go.
c) It is God's unique way of making the sky more beautiful to those watching from below.
d) There is no known reason for birds flying in formation.

What do birds need to do before leaving for migration?
a) Eat lots of food and store up fat to be used for energy in flight.
b) Study the behavior of similar birds to determine in which direction to fly.
c) Grow extra feathers to provide extra lift for the long migration.
d) Sleep for extended periods to reserve energy for the flight.

How does a bird find its when during migration?
a) All of these answers are accurate.
b) Sun and stars
c) Magnetic fields
d) Landmarks

What is the ability for a bird to reach its destination without getting lost called?
a) Homing instinct
b) Horning instinct
c) Honing instinct
d) Migration instinct

What causes birds to migrate?
a) God gave them the instinct to move to a different location for a certain season.
b) Man has developed annoying patterns that alter the birds natural habitat.
c) Man-made feeding boxes are placed along migration routes at the right time to encourage migration.
d) None of these answers is accurate.

What is migration in birds?
a) The twice-a-year process of a bird moving to different locations for different seasons of the year.
b) The process of moving from Mexico to the United States.
c) The gathering of birds on a thermal wave/wind to circle around potential food.
d) The undulating pattern that birds use when flying in an up and down pattern (like a finch).

What does a bird use its tail for when flying?
a) Steering
b) Flapping
c) Undulating
d) Parachute landing

What is it called when a bird rides the waves of heat called thermals that lift it higher and higher in circles?
a) Soaring
b) Flapping
c) Gliding
d) Undulating

What is it called when a bird holds out its wings in a straight manner and sails through the air?
a) Gliding
b) Flapping
c) Soaring
d) Undulating

Where are a bird's flight muscles located?
a) In the chest or breast of the bird.
b) In the wings of the bird.
c) In the wings and tail of the bird.
d) In the neck and legs of the bird.

What does flapping do for a bird in flight?
a) It helps the bird produce the thrust needed to overcome drag and speed up, which provides lift.
b) It slows the bird down, which reduces lift, and allows the bird to land.
c) It lets the bird search for food and migrate while saving energy.
d) It catches the thermal winds that will keep the bird in a nearly perpetual circular pattern.

How are bird bones different from the bones of other animals?
a) They are hollow and light with thin brackets running across them to strengthen them.
b) There are fewer bones per square inch of body to allow them to fly more fluidly.
c) They are filled with special air that adds lift during flight.
d) They are dense, which allows the bird to gain more thrust when taking off.

What do vagrant birds have in common?
a) They are birds that end up where they have never been before on their migration.
b) They are lazy birds.
c) They are birds that soar at the highest elevations.
d) They are birds who are likely to return each year to the same location.
