Hello, everyone

Summi

I made short video of Karl II lovely nest work this morning

Crissy, thank you for the video! Karl II is a real joy to observe.

...
eggs are still silent. I have to be patient

Liz, thank you very much for the nice pictures.
Karl II has been very diligent again, this morning.
Patience is no problem for you, is it?

The eggs are well hidden. It will be hard to see the first cracks.

10:52 Kati takes care of the nest


10:52 Something itches again. The eggs are hardly visible.


10:58 Brooding, brooding, brooding...

[Liz01]

Crissy, thanks a lot for the video

11:57 Kati is preening herself


12:01 she has still a lot of work

[Liz01]

....The eggs are well hidden. It will be hard to see the first cracks.

Anne, Yes, Karl II is very active . he knows, that it getting serious

We will hear the little one, before there is a crack quack quack.. like an frog or duckling.

Yes, "quack quack", I know, we will hear the egg talk before the first chick emerges from the shell!
But I really hope we can also see the whole process.
The first pip, the cracks, the birth.

If Karl II is as enthusiastic about catching fish as bringing moss, we will see whales this year.
I cross my fingers.

I would like to recommend everyone reading this very nice article.
The Art of Hatching an Egg, Explained
https://www.audubon.org/news/the-art-ha ... -explained

"... Hatching is the climax of incubation; indeed, it is the climax of both fertilisation and incubation and the third great landmark in the life of an egg. How does the chick break out from the claustrophobic confines of the shell? Our mental image of the process has been corrupted by cartoons, where attempts to romanticise and sanitise the process often show a hen’s egg with its top neatly popping off to reveal a warm, yellow fluffy chick. The reality is not like that. It is still pretty remarkable, but it isn’t as quick, as clean, or as simple as we have sometimes been led to believe. ...

... Before starting to break out of the egg the chick has three things it must accomplish. It must first switch from being dependent on the oxygen diffusing through the pores in the eggshell into the network of blood vessels that line the inner surface of the shell and start to use its own lungs to breathe. The chick takes its first proper breath and fills its lungs the moment it punctures the air cell inside the top of the egg. This step is essential because by this stage of development there is not enough oxygen diffusing through the pores in the shell to support the chick’s respiratory requirements. Taking a breath from the air cell provides the oxygen and the energy necessary to break through the eggshell.

Before it takes that first breath, the chick has to start shutting off the blood supply to the network of blood vessels that line the inner surface of the shell, and withdraw that blood into its body. The blood vessels are programmed to close off at the point where they emerge from the bird’s umbilicus, and just before the chick starts cutting round the shell.

Third, the chick has to take what is left of the yolk and draw it into its abdomen. It does this by sucking up the remaining yolk through the stalk that connects the yolk to the chick’s small intestines. This "yolk sac" is a food reserve for the first few hours or days after hatching.

Essentially, the chick has to do what a human baby does as it switches from dependence on the placenta for both oxygen and food to independent breathing with its lungs and the ingestion of food through its mouth. Thinking of it like that, it is a pretty major transition. ..."

Yes, Kati heard something.
Please, no unwanted visits today!

I think it's OK

I looked up the hatching times in previous years, on this nest.

In 2016 the 1st egg was laid on 12.04 and hatched the night of (16-17).05 (after 34-35 days)
In 2017 the 1st egg was laid on 17.04 and hatched the night of (19-20).05 (after 32-33 days)
In 2018 the 1st egg was laid on 16.04 and hatched on 18.05 (after 32 days)

This year, 2019, the first egg was laid on 12.04
(Today is 32 days later, the average of previous years is 33 days)

13:40:34 She keeps a close eye on the environment

[Liz01]

Anne, when did they start breeding? Right at the first egg or from the second egg. Do you know it ?I'll go back to this time.

Liz, I think intensive breeding started after the second egg was laid.
Until then, the first egg was not permanently covered. In the evening, Kati and Karl II sometimes stood upright next to the egg, for a while.

Than you Anne. I saw it right now..

30 days after they start breeding. We will know it soon.

[Anne7]

Thank you Anne. I saw it right now..

Yes, we will have to wait and see.
I am personally impatiently waiting for the first "quack quack".
I heard nothing, so far.

We must also remember that there was that strange night when Kati did not permanently cover one (or maybe even two) eggs.
We do not know how long they have been in the cold, that night (20-21).04.

and here, in the early morning:

In 2016 the 1st egg was also laid on 12.04 and hatched the night of (16-17).05 That's after 34-35 days.

[Summi]

Thank you to everyone for the pictures, reports, comments and video by Crissy.
It's amusing to see the tireless Karl II fortifying the nest, most of all the side near the cam to block the view and stop us to poke our nose in their private family matters.

new male (another genes) ...It takes 32 to 38 days for black stork eggs to hatch.
yes, we will see soon

Hello, Solo
Have you seen BS nests where the first egg only hatched after 37 or 38 days?

15:34:47 Back on the eggs

Hello, Solo Have you seen BS nests where the first egg only hatched after 37 or 38 days?

no, I know only few (6) BS nest with stream and I haven't hatch statistics
6 day scatter for BS: 32-38 days (and WS: 28-34 days) is in scientific papers

[Solo]

...But I really hope we can also see the whole process.
The first pip, the cracks, the birth....

that will be very nice, but it is very unusually to see that all
previous year we had this great opportunity on HU, Gemenc-Keselyűs nest (video: https://youtu.be/Hmyz0ndhkA8)

I think that is meant that (normally) 32-38 days after the start, the complete clutch hatched.
In fact, if there are 4 eggs in a nest, the fourth egg is laid 6 days after the first. But it already hatches 3 days after the first egg. This means that the 4th egg is incubated less time (3 days shorter than the 1st).

that will be very nice, but it is very unusually to see that all

Yes, I have seen that.

I have no sound from the webcam. Does anyone else have this problem? It was OK this morning.

OK. It came back after the next lot of buffering.
