•The migration of people out of a country.
•The migration of people into a country.

•the regular, recurrent, seasonal movement of populations from one geographic location to another and back again.
I have been thinking of ideas around emigration/migration and looking at bird migration. People left Handa at a time of famine and those that emigrated arrived at Cape Breton at a time of famine also.
' hungry birds do not set off on migrations if food supplies diminish they may move to find a better source of food'
'a bird needs a reserve of fat in its body to be able to travel long distances especially those on non stop or very long flights'
'many birds double their weight before migration while larger birds will gain less than this'
