Very few cranes reported on migration the last two days , the weather is still too warm and the wind in the wrong direction .

Very few cranes reported on migration the last two days , the weather is still too warm and the wind in the wrong direction . Agree completely. Compared with the last twenty or so years this November is remarkably mild and the wind has generally been unkind to the migrating birds. Although we have seen a few thousand spread over the past weeks there hasn’t been the two or three days of nonstop flights of birds over our house. I have seen a few squadrons clearly fighting the wind and heading off the normal direction. I am sure they will sort it out. |

We've seen precious few this year so far, but today several hundred flew overhead around 3 o'clock - making a load of noise. Lovely to see and hear them, though it's a sad thing to see them leave.

We had 422 fly over the house mid afternoon, the first flight directly over the house this year.

@ Nifty, a quick snapshot, simple smartphone, not a high resolution pro camera with zoom lens. I was not criticising the photography. With unequal spacing like that the birds are obviously rookies and need more drill! |

I am afraid that this info is only for the cognoscenti who would not need an explanation. seeing as you have liked me and that yesterday was so relevant, I’ll give you a clue en.wikipedia.org/wiki/Drill_commandsStop Press The latest from OHQ is that they are going east. |

Whatever !  "The cranes have started on their migration again , the wind is a lot less than last week . Les grues partent en nombre des lacs de Champagne et la migration est très marquée sur l'axe traditionnel. Certains observateurs ont ainsi pu dénombrer plus de 5 000 grues en quelques heures et même plus de 11 000 à Flavignac. Le soir environ 5 000 grues sont présentes à Lachaussée." I observed a few passing over very low this morning. |

They have indeed. This our last full day here in France and we spent most of it tidying up in the garden. There was a steady stream of grues in formation heading southeast on their usual track. Lovely to see them taking advantage of the gentle flying conditions and using the local thermals to spiral upwards. Maybe we will catch them going in the opposite direction early next year.

Have been out for most of the day but upon our return 731 flew over the house on the way to their 'olidays.

Cranes on the move en masse since Sunday , still being blown East to cross the Med.
We have seen a few flights passing yesterday but not the usual thousands on this flight route.

‘Flight speed : 40 to 80 km/h (so they can cross France in less than a day)
Flight altitude : from 200 to 1500m
How are they oriented during migration?
According to studies on migration in France ,
Migratory birds navigate in part by sensing the Earth's magnetic field.
They could also orient themselves with respect to the stars or with respect to the sun .
They would also be able to take topographic landmarks that they would learn during the first trip.
Magical or practical?
, wouldn't we, too, be able to do it unconsciously if we took the trouble to open up to our environment? ‘
How do they do it?
Who set up the programme ?

There has obviously been an error somewhere en.wikipedia.org/wiki/Les_CraneHonestly, who writes this stuff? ’ was outspoken and outraged some callers by hanging up on them. ‘ |
