Migratory bird genetics - how do birds find their way?
Research Report 2016 - Max Planck Institute for Evolutionary Biology
Migratory birds travel precisely over thousands of kilometers, often across continents, to a wintering area where they have never been before. And that without the help of her parents, but with admirable accuracy. How do you do that? Breeding trials have shown that the migratory direction and timing of bird migration have a genetic basis. So the bird knows when to fly in which direction for how long and to land in warmer climes in time in winter. We want to understand which genes play a role here.
............
migratory behavior has a genetic component
The breeding experiments clearly show that offspring of selectively mated parents show the same migratory behavior of the parent generation. Figure 2 shows an example of the inheritance pattern for different tensile directions. Offspring of selectively mated Southeast migrants (SO) are also SO-oriented, correspondingly, they behaved selectively bred southwest migrants (SW). The descendants were raised without contact to their parents, a learning component by the parents can thus be excluded; the orientation behavior of the juveniles was based exclusively on the inherited information.....

Particularly exciting is the result of the crosswise mating of SO and SW pullers: The offspring of these crosses show an intermediate tensile behavior with a medium orientation direction. This pull direction is very likely to be highly selective in nature, as it leads the birds across the Alps during the autumn migration, and the birds along this migration route must cross the Mediterranean and the Sahara at their widest points. All of these are significant ecological barriers that a bird avoids in nature.

Thank you, Hellem!

Thanks a lot, Liz!
This is indeed very interesting info.

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 (SE) and southwest (SW) 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, Maru, Karula too - but in this report are Eurasian blackcaps not black storks
Tamás, Enikő Anna say in her dissertation:
Eastern route 80%, Western route 15% and the remaining 5% spends the winter in Europe or migrates through Italy in the direction Tunisia, Lybia ("mediterian route") - less than 0.1%.

birdmap update on 19.August:
Oru 1106 km, Aru 154 km - Aru flew 1km only (it was 153km yesterday ) Maybe Aru likes it there, in Latvia)). Don't want to think of any problems with its wound.. Thank God, the weather's gonna be fine end of August . Good for Aru !

Some info about Oru’s location.
(Apologies for potential mistranslation due to GT)
“Nature Reserve Warzewo”
Warzewo – a faunistic Nature Reserve located in the municipality of Podedno, in the district of Parczew, in Lublin Voivodeship[2] .
The Warzewo Reserve is a water-peat nature[3]. 60 species of birds were found on the site, including: 26 Breeding and 9 probably breeding animals[3]. There are m.in.: Grebes (grebe i little Grebe), 6 species of ducks, a bud, Marsh Harrier, Łska, Common Tern, seagull, Sea Buckthorn, Potrzos, czajka, załucka, Bekas Snipe, and from the unbreeding species: meadow mudk, Snipe, Kulik Wielki and Battalion[3] .
Google Street View
The Nature Reserve is the woods in the distance behind the fields.

Hello together,
thanks to everyone for the interesting informations, the updates, trackermaps, pictures and the summary!
Ari, your pictures are beautiful. This seem to be nice places for young Black Storks, Arus and also Orus location. There's a lot of forest, thank God only small roads, and the pond where Aru is, looks inviting.
I'm not worried at all about Aru staying there for some days and not flying on. He is a young bird who has just discovered his freedom and he is certainly amazed at how the world outside of nest looks like. Aru has to orientate himself completely new. And he must certainly practice catching fish and improve his skills. Therefore it is certainly advantageous not to fly hundreds of kilometres, but to practice fishing at the first good resting place.

good evening,
Have just looked at the Tracker Map of Aru, there is always Speed 0, that means now he is from yesterday until this evening only on foot?
Yes Anne 7 and Gigi we look at the maps

I don't think Oru is on a walking migration!
It must be a fault in the transmitter.

Hello Jo,
Bibibu wrote about Aru, who has - as far as I've seen - almost the whole day a speed of 0.
Oru has a normal speed, he's not walking.
Bibibu, there are some points on the trackermap where Aru has a speed of 26 and 35 km. But you're right, mostly it is 0. This even on longer lines on the trackermap where I would expect a real flying speed. It's indeed a bit strange. But I think it must be a problem of the trackermap or the transmitter.

I don’t know, Michi.
The photos are from Instagram with the hashtag of the village name. (#Eglupe)
It looks the home of some tunneling animal... Badger, martin, fox...?

Thank you for the info!
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!
