NEST HISTORY:
This stork site has only been in existence for two years. For the first time there was a successful breeding in it this year.
It was rebuilt by members of the Eagle Conservation Committee on March 14, 2023 as it had almost completely fallen down. The male returned from migration on March 21, and a day later Skierka appeared at the nest.

streaming started:

The camera was placed at the nest in a single old sessile oak before the arrival of the storks in mid-March, but for technical reasons the online transmission was not possible from the very beginning.

SEASON 2022 (overview on this first page) viewtopic.php?p=4405#p4405)
new nest for Skierka and new male named Bolek in Bolewice Forest District
female Skierka spends the winter regularly in Greece on the Struma River near the Kerkini National Park in Macedonia. On March 4 (2022), she began spring migration to the north. She came to the nest in Wolsztyn on March 12 (2022), but did not find the male Titan, who appeared at the nest only on April 30. That is why Skierka flew several nests and on April 1 she met the male BOLEK, with whom she started the brood.

and next info

10:32 AM bociany czarne
​Tam, gdzie jest obecnie Skierka nie ma kompletnie zasięgu, ale ... zamontowaliśmy tam fotpułapkę, więc materiał (tylko zdjęcia) się zgrywa. W połowie sezonu zgramy wszystko z kary CD i udostępnimy.

Where Skierka is now, there is no coverage at all, but ... we have installed a camera trap there, so the material (only photos) is being uploaded. Halfway through the season, we'll rip everything from the CD penalty and make it available.
(without correction now)

edit
10:38 AM bociany czarne
​Nowe gniazdo Skierki jest oddalone od tego w Bolewicach z 2022r. o 6 km, natomiast od tego z 2021r. w Wolsztynie o 25 km.

Skierka's new nest is far from the one in Bolewice from 2022 by 6 km, and from the one from 2021 in Wolsztyn by 25 km.

Oh that's interesting!
Although I already got the impression last year that Skierka is the kind of girl who likes to keep her options open :D

Now we keep our fingers crossed for dear Bolek and that he finds a new girlfriend too ;)

yes, Bolek and Tytan too; they both are good males - fathers, excellent food providers

Skierka: do you mean her visit at the end of the season to the nest in Wolsztyn?

I meant with Skierka how she also visited several nests before the season last year. And also how she has chosen 3 different partners by now when they usually say that a stork pair remains together for more than one year and return to the same nest. (For example Karl2 and Kaia)

I guess that happens when a female arrives much earlier than male partners and she has no other choice to look for a suitable breedibg place herself ;)

It's very individual even with ringed storks - not all are faithful to the nest, but that's more usual.
Only some males wait even longer for their previous partner. They will usually accept the first female that flies into the nest (if they are mutually attractive ;-) ).
Skierka seems to be a confirmation of how strongly hormones work - and therefore the need to find a partner, a nest, where the reproductive process can begin.
