There are 4 bird families living near the mountain. 
2 bird families flew away to Africa. 
That means that 28 bird families flew away to Asia. 
Now we need to find out how many more bird families flew away to Asia than those that flew away to Africa. 
To do this, we need to subtract 2 from 28. 
28-2=26
26 bird families flew away to Asia than those that flew away to Africa.
