Scientists have long debated why migrating birds fly in a V formation.
Maybe its to ‘‘draft’’ each other, to catch the one in front’s updraft, to save energy during the flight.
Maybe it’s for protection - safety in numbers.
Maybe they’re just following the leader.
But what happens when the leader gets tired?
It seems sensible - and birds are much brainier than we think - that they would swap positions to give each other a break.
They also honk a lot.
Maybe it’s to give each other encouragement: ‘‘Come on you guys, it’s not far now.’’
(Or: ‘‘Look out, large aeroplane to starboard.’’)
Farmer-author Doug Avery, who wrote a book about resilience, says in times of adversity, such as drought, you’ve got to choose your Vmembers.
You’ll carry them, and when you can’t, they’ll carry you - and you should let them.
It’s about sharing the burden. Who would be in your V? Mary-Jo Tohill
