EGGS- laying
(2025: 1st egg - 12.04, 13 days after female's arrival, 5 eggs)
previous years: viewtopic.php?p=43571#p43571
Darius Anderwald:
Komórka jajowa od zapłodnienia musi przejść proces otoczenia białkiem i pokrycia się skorupką. Proces ten przebiega u bocianów czarnych 2 dni.
Once a black stork’s egg is fertilized, it needs about two days to form its protective layers — first the protein coating, and then the shell itself.

CHICKS - hatching
2025: 1st chick hatched on 17.05, 35 days after laying the first egg
Darius Anderwald:
Średni czas wysiadywania od złożenia przez samicę 1-go jaja do wyklucia się 1-go pisklęcia to 35 dni
On average, it takes about 35 days from the laying of the first egg until the first black stork chick hatches.

Klucia pierwszego bocianka możemy spodziewać się około 2 maja (28.03 + 35 dni inkubacji = 02.05).
We can expect the first storklet to hatch around May 2nd (March 28th + 35 days of incubation = May 2nd).

Skierka (from laying of the 1st egg):
2025 - 35, 2024 - 37; 2023 - 34; 2022 - 36 days
btw. 2024: 5 egg, 5 chick hatched - 4 on the same day (!), 5 fledged

Location & residents

LOCATION

NEST

This site is located in the Bolewice Forest District in the Pszczewskie Lakes and Obra Valley Natura 2000 Area. It was rebuilt by members of the Eagle Protection Committee on March 14, 2023. Previously, for two years, only single birds appeared there. The camera was placed at the nest located on a single old sessile oak tree before the arrival of the storks in mid-March 2023. Skierka started breeding with Królewicz.

RESIDENTS

"o Królewiczu nic nie wiemy. Skierka pochodzi z centralnej Polski z Puszczy Bolimowskiej z Nadleśnictwa Skierniewice, gdzie osobiście zakładałem jej logger nożny Rodzice nie byli zaobrączkowani wiec nic o nich nie wiemy."

"We don't know anything about the KRÓLEWICZ/Prince. Skierka comes from central Poland, from the Bolimów Forest in the Skierniewice Forest District, where I personally installed a foot logger on her The parents were not ringed, so we don't know anything about them."

SKIERKA
a ten-year-old female (10 CY/hatched 2017) who comes from the Skierniewice Forest District in the Bolimów Forest (Puszcza Bolimowska). There she was ringed and even had a GPS transmitter on. (Previous years we follow her with the "name" BOCZ 07 ŻÓŁTY - Yellow, because she has yellow transmitter.) The female joined her first successful brood in the Wolsztyn Forest District, i.e. about 300 kilometers to the east from her place of origin.

opis pod streamem/filmem
"W 2026 roku samica wróciła do gniazda 5 marca i na razie pojawia się w nim rzadko. Większość czasu spędza na żerowisku."

In the description below the stream, there is information:
"In 2026, the female returned to the nest on March 5 and for now appears in it rarely. She spends most of her time at the feeding grounds."
