- 10.35.52 drugi młody z loggerem wchodzi tak wysoko na środkowy konar, że go nie widać
(10.35.52 the second youngster with the logger climbs so high onto the middle branch that he cannot be seen)
- 10.38.19 schodzi trochę niżej, widać go na konarze
(10.38.19 it comes down a little lower, you can see it on the branch)
- 10.41.46 odlatuje! To chyba jego pierwszy lot?
(10.41.46 departs! This is probably his first flight?)

Hello everyone
CHICKS
- 1st chick: 73 days old - VX7911 + lokalizator nożny / legtransmitter MAIDEN FLIGHT on 19.07 - 71 days old
- 2nd chick: 73 days old - VX7912 + lokalizator nożny /legtransmitter
- 3rd chick: 72 days old - VX7910 + 1FT4 (readable white colour-ring) MAIDEN FLIGHT on 19.07 - 70 days old
- The chicks become capable of flight at the age of 68–72 days (maiden flight). Starting a flight depend on more factors.
- Młode uzyskują zdolność do lotu w wieku 68–72 dni (pierwszy lot). Rozpoczęcie lotów zależy od większej liczby czynników.
- Przed ostatecznym odlotem na migrację młode bociany początkowo latają średnio na odległość do 200 metrów, a wraz z wiekiem dystans ten zwiększa się średnio do 500 metrów.
- Before their definitive departure for migration, the fledglings initially fly within an average distance of up to 200 meters, and as they get older, this distance increases to an average of up to 500 meters.
Age at permanent departure / Wiek w momencie ostatecznego odlotu (na zawsze):
• Average: 87 days / Średnia: 87 dni
• Range: 73 to 108 days / Przedział: od 73 do 108 dni

-Lepsze wyniki w przeżywalności osiągają te pisklęta, które po opuszczeniu gniazda spędzają w nim więcej czasu – oznacza to, że wracają do gniazda i stopniowo się usamodzielniają, ale wciąż są w nim karmione przez rodziców. Przez kolejne 2–4 tygodnie po uzyskaniu zdolności do lotu wracają do gniazda na noc lub odpoczywają w nim w ciągu dnia.
- Better results are in surviving of the chicks which spend longer time in nest after fledging, means they return to the nest and step by step get independent, but are still getting food from parents in nest. For another 2-4 weeks after being able to fly they will go to the nest at night or rest at the nest.

Re: Połczyn
FEEDING
Młode uczą się szukać żerowisk i zdobywać pokarm dopiero po definitywnym odlocie z gniazda (migracja).
The juveniles learn to search for foraging sites and acquire food only after their definitive departure from the nest (migration).

21:14 @wiesia-R 21.12.28 przylot Bawarki - @MKmatylda Nie było tego dużo - ale dla jednego to już dobra porcja - @MKmatylda Ostatnio wczoraj rano jadł

youtube chat info - thx to everyone - wielkie dzięki za Wasze raporty 
NEST ACTIVITY LOG 22/07/2026 (in the evening - the whole day)
Log compiled from chat observations and structured with the assistance of Gemini AI.
male Mieszko - female Bawarka
Chicks:
Wanda: ringed with a white colour-ring 1FT4 (no logger).
Ziemowit & Oda: both equipped with leg-transmitters (loggers).
04:00: A single fledgling (Wanda) is visible in the nest early morning.
05:37: Wanda departs the nest for a short morning flight.
07:44: Wanda (1FT4) returns to the nest.
09:04: Wanda departs the nest again.
11:14: Wanda arrives at the nest (11:14:17), followed shortly by adult male Mieszko (11:14:39). Mieszko departs at 11:14:56 without feeding.
11:28: Wanda returns to the nest (11:28:35).
11:28: FEEDING (1). Adult male Mieszko arrives (11:28:58) and delivers food (small fish/items) to Wanda. Mieszko departs at 11:29:46.
12:36: Wanda shows signs of distress and defensive posture (ruffled feathers, bill clacking, ... scanning below the nest).
12:39: Wanda flushes in panic from the nest; off-camera wing fluttering and scuffling sounds suggest probably a predator disturbance. The nest remains empty for several hours.
19:08: Fledgling Ziemowit arrives at the nest (19:08:05) after an extended absence.
21:12: FEEDING (2). Adult female Bawarka arrives at the nest (21:12:28) and feeds Ziemowit.
21:20: Audio echo on the stream created temporary confusion regarding multiple fledglings begging outside the frame; only Ziemowit was present on the nest.
22:23: Ziemowit settles on the nest alone to spend the night.
Daily Summary
Nest Attendance & Absenteeism:
Nest occupancy was unusually low today. Only fledgling Wanda (1FT4) was present during the morning and early afternoon. Fledgling Ziemowit returned in the evening at 19:08 after an extended absence (nearly 33 hours since his previous departure). Fledgling Oda was absent all day.
Flushing / Disturbance Event:
At 12:39, fledgling Wanda exhibited defensive posture (ruffled feathers, intense downward scanning) before flushing in panic from the nest. Observers noted fluttering and scuffling sounds off-camera, suspecting probably an interaction with a predator/raptor.
Feeding:
A total of 2 feedings were recorded: 11:28 – Adult male (Mieszko) delivered a small feeding (Wanda present). 21:12 – Adult female (Bawarka) delivered food (Ziemowit present).
Overnight Status:
Ziemowit remains alone on the nest for the night. Both Oda and Wanda spend the night outside the nest.
Discussion & Observer Notes
Predator Alarm vs. Human Disturbance:
Following Wanda’s sudden flushing at 12:39, extensive discussion arose in the chat regarding the cause. Observers speculated about potential human interference. The moderator (marika.marika) clarified that the fledgling’s defensive posture (ruffled feathers, bill claping, ... intense downward scanning) specifically indicates a reaction to a natural predator (bird of prey) in the vicinity, rather than human presence, to which storks typically respond by silently flying off.
Stream Audio Echo / Delayed Sound:
Between 21:00 and 21:20, several observers reported hearing multiple fledglings begging simultaneously off-camera, leading to false assumptions that Oda or Wanda were nearby. This was identified as a technical stream artifact (audio latency/echo doubling Ziemowit's vocalisations).
Monitoring Protocols & Expert Consultation:
Due to the extended absence of the two logger-equipped fledglings (Ziemowit missing for nearly 33 hours prior to his return), observers were assured that Dr Dariusz Anderwald (KOO)—who is the only one with direct access to the GPS tracking data—would be contacted to check the situation of the missing fledglings if they did not return by the evening.
