Hi All
I guess they have to fly at night but what do they do when its really really
dark or there are clouds in the way or both. I find migration fascinating and
so have gone on a bit on my blog "Top Birds & Everyfing" about the problems
birds face with night and cloud. I've also posted some links to earlier posts
on bird navigation because it's also part of the general subject. You may or
may not find some alternative opinion interesting. Grab a beer, cuppa, cafe or
a dram and have a read if you've got the time or inclination…

It is easier to go down a hill than up,
but the view is from the top.
