Scientists have studied the (1) flocks of geese and realised what teamwork looks like.

Geese can reach the destination more quickly and use less energy if they (2) migrate and fly together in this formation.

When flying together, each goose provides an extra upward lift for the goose flying behind. This allows the whole flock to fly (3) further with the same amount of energy than if each goose flew alone.

When the goose at the front of the formation (who uses the most energy) gets tired, it (4) moves to the back of the group. Another goose then becomes the (5) leader at the front.

If a goose becomes sick or injured during (6) migration, two geese will (7) remain behind to look after the weak goose until it can fly again.

It seems that geese can teach us a lot about teamwork and also about caring for each other's well-being.
