Clip Description

Birds often flock together because there is safety in numbers. Flying in a large group, with many pairs of eyes on the lookout, makes it easier to spot a potential predator. It is also harder for a predator to single out an individual bird.

In this fascinating clip, we see over 100,000 starlings twisting, turning, swooping and swirling across the sky in beautiful shape-shifting clouds. This hypnotic spectacle is called a ‘murmuration’.

Whiteboard Number Challenge

In the clip, we are treated to an incredible aerial dance called a murmuration.

Give each letter of the word ‘murmuration’ a number according to its place in the alphabet.

e.g. A = 1    Z = 26

What is the total value of this word?
