Ari, this may be. Nevertheless it looks strange. But we're not finding out what it is. :)

Solo, there are no investigations on black storks. There are also few findings. they tested it on a species.Solo wrote: ↑August 19th, 2019, 8:55 pm Liz, thanx very much
why they choose (Päike and others) they way to Italy (or Greece) and mostly perished
" Particularly exciting is the result of the crosswise mating of Southeast and Southwest flyers: The offspring of these crosses show an intermediate tensile behaviour with a medium orientation direction."
so maybe Kati is westflyer? Karl (I) was eastflyer - but in this report are Eurasian blackcaps not black storks
Good morning Liz,

I thought I saw the screenshot before, but couldn’t find it again.You are right, the pond is located closer to the railroad. That must be Aru’s pond in the Instagram videos! Yes!It seems that Instagram is be a good place to find photos by location.Thank you for sharing!
Solo, I have no idea if Kati could be west migratory bird. I saw Päike's flight ... but she might have followed a group of birds?
Aru had cloudy all day (no rain)Liz01 wrote: ↑August 20th, 2019, 6:39 am I do not know what the thermals are like there. Maybe ARU has problems starting from the ground. Starting from the ground is much exhausting, more exhausting than starting from the nest or tree. If Aru is staying in the pond overnight, he is safe from Fox ect.
But it also shows that something is not quite so how it should be. They prefer to spend the night on trees.
yes, nothing is sure, Kati hasn't transmitter - it was only though, if ...("Particularly exciting is the result of the crosswise mating of southeast (SE) and southwest (SW) flyers: The offspring of these crosses show an intermediate tensile behaviour with a medium orientation direction." Päike - medium direction, Karl - eastflyer and Maru, Karula too)
I understand what you want to say. It is possible. But unfortunately not sure. I wish she had a transmitter. She is an adult brooding female. We only have Mare. she is left over from all the female with transmitterSolo wrote: ↑August 20th, 2019, 8:46 am yes, nothing is sure, Kati hasn't transmitter - it was only though, if ...("Particularly exciting is the result of the crosswise mating of southeast (SE) and southwest (SW) flyers: The offspring of these crosses show an intermediate tensile behaviour with a medium orientation direction."

wiki: Thermals are columns of rising air that are formed on the ground through the warming of the surface by sunlight ... Thermals can also be formed in a line usually because of the wind or the terrain, creating cloud streets. ...
Solo,
Thank you very much for the magnetic migration texts, Anne :)Anne7 wrote:...
sometimes it would be interessting to sit on a little stool and just watching what happens...gThe magnetic north pole of the earth moves - and with increasing speed. This is reported by geoscientists of the US space agency NASA. While at the beginning of the 20th century it was still around 16 kilometers per year, today the Pole is moving 55 kilometers per year towards north-north-west.
The measurements indicate that our planet is facing a reversal of its magnetic field - that means, it is turning its direction 180 degrees. The magnetic south pole becomes the north pole and vice versa.
Last measured pole shift 780,000 years ago
[...]
Studies have also shown that over the past century, the magnetic north pole has shifted about 1100 kilometers from Alaska towards Siberia.
But perhaps apart of the magnetic influence it had an influence, that since these days the wind is not any more string and straight South > North, but instead of this more West > East, SW > NE. And e.g. today it is less wind than yesterday.Interessting that all three storks Oru, Aru, Eedi have in nearly the same time not flown ahead further but something like a rest.
