They are saying 'farewell until the next time'.:-)
Hopefully. I'd like to see and hear them return.
They may be mournfully calling out "Not again, not again, not again...."Or even, "Stuff this for a game of soldiers" an expression that may not be familair to you, but it is to ducks and cranes and geese... (and soldiers, obviously).
I do wonder why they call out so much
So do I. And I'd like to know if they are calling out all time on their way back in southern regions.
Do some of them live long enough to return to the same spot? I thought they only had a day or two of adult insect life...........http://www.telegraph.co.uk/news/earth/wildlife/3307701/Crane-fly-emerging-later-due-to-climate-change.html.
Ha ha ha, Claude. It's Hallowe'en, eh? :)
