- If it is stiff headwind (and birds would have to spend much more energy), they stop and wait for better weather conditions. This also applies in the case of rainy weather and other negative factors. .... - Anne, that is scientific fact, no too early conclusion
Solo, as I said myself, it is far too early to make any conclusions.
(I mean on our own observations here)
It will take weeks or months to see any correlations.
We will see how the weather and the wind directions are when our BS fly southwards. And also when they take a break.
This is a little experiment. Some additional information.
Of course, they will most probably suspend their flights when there is a strong headwind or rain... I'm glad that we agree on that.
But what happens when there is a moderate headwind? Or no wind at all?
Or wind from the west or from the east?
And when will our BS decide to continue their journey?
Are they just waiting for favourable weather, right now?
Will they fly longer distances if they have strong tailwind?
This kind of observation is interesting, I believe?
