I adore this close up. Look at that funny 'smile' on his face, so cute!

17:13(-14) Usin made very nice jumps

17:30 only one feeding till now? Is Kati gone?

[Liz01]

17:45 Karl comes feeding... very bad stream today






Anne Thank you very much for the data That helps me a lot.

They are really very late in this year! So we can see what happens, when there is a lack of food.

[Anne7]

Liz, yw

Yes, they are very late, I agree.

It hasn't been easy for the parents and the storklets:
One more chick than last year in the nest, that means 17% less food for each storklet.
And also very cold and rainy weather for a long time, in combination with several days of very little food...
The storklets are still a little lighter than usual, still catching up, I believe?
Yes, raising 3 storklets is really a maximum in this nest, in this climate...

Karl and Kati did a great job. It took them about 10 days more than last year.
But they managed. Nearly finished their job now.
(Possibly Kati left today? In that case, Karl will have to do all the final work.)

[Liz01]

Kati is still here

18:59 Kati brought frogs and fishes

[Anne7]

Kati is still here

Liz, I believe this means that both parents think the kids are still not weighting enough, not ready!?
Clever parents, we can trust them. They do whatever they can to make sure the kids have the best possible chances to survive their first migration.

[Liz01]

Anne of course, everything is in order. I have great confidence in the instincts of the animals. They know what they are doing.
It's just so, the longer all stay, the lower is the likelihood, that they will not survive. This is not my opinion. I read it at Maris Strazds.
No rule without exception. Our guys will survive

[Anne7]

OK. I didn't know. That's interesting. Maris Strazds is an expert.
And what is the explanation he gives for this statement?
Did he also write something about the reasons why he believes/knows this?
Or is it a conclusion after many observations?

[Hellem]

19:59 Tali is jumping: nest - left branch - nest - left branch - nest - tree trunk - left branch etc.

This is the result of his observation.
Ziluka is born very early in 2015. So they thought, that she had very good chances to survive. She had a transmitter. The transmitter does not send any more data since November 2015 ...
So, a early birth is also not a guarantee.

[Anne7]

For the courageous ones among us.
Here you can find a very interesting doctoral thesis (2012) on black storks. (pdf 146 pages)
On breeding, migration, survival rates...

http://www.dravaszovetseg.hu/downloads. ... file_id=58

Black Storks breeding in north-eastern-Europe and western-Asia use the eastern shorelines of the Black Sea to migrate near the Caucasus through Turkey and Israel to Africa. Janssen et al (2004) reports that a high number of Black Storks can be observed using this route. It is supposed that a part of these birds come from the Baltic, other part from Russian and Ukrainian breeding grounds.

Black Storks often suspend their autumn migration for several days, even weeks, supposedly in case they find a suitable refuelling site. Identified (colour-ringed) Black Storks using stopover sites in Israel spent 9 days at the site on the average, with a maximum of 29 days (van den Bossche 1996).

On the Eastern route, according to the counts carried out in Israel between 1988 and 1995, the start of fall migration is in the beginning of August, and the end is in the end of November.The most Black Storks cross Israel in the second half of September and first half of October (even a daily 1000 individuals, the maximum counted was 1821). Migration peaks of adults and young birds are not the same in Israel, as adults arrive sometimes even 2-3 weeks earlier (pers. comm. van den Bossche).

August 03


Good morning!

The storklets are all very active in the morning.
Uno is preening in the nest.
Tali is on the left, Usin, on his favorite branch.
Liz is finding her magnifying glass.

Dear Anne7

Thanks for the information and highlights, that's very helpful and relieved.
By the way, I'd never thought that I would read a thesis of aves someday.
Really appreciate

[Liz01]

Good morning to all

6:58 Tali flew away


orinpix Slowly I wake up

[Liz01]

................. the start of fall migration is in the beginning of August, and the end is in the end of November.The most Black Storks cross Israel in the second half of September and first half of October ............[/i]

Anne, this is what we see in the Bird Map and Goris. They start at the beginning of August and spend long time at different places on the way to the south.

Ziluka (Upene) was a very long time in Poland and the Czech Republic. She leaves the area in the end of september. In the october she was in bulgaria...then she flew straigth to the south.. she crossed the Marmara Sea and flew to Israel. She took a long break at the fish ponds.

EDIT: I will read the doctoral thesis when I have holiday. Thanks for the link This certainly will be very interesting.

[Liz01]
