NEST ACTIVITY LOG 23/07/2026 (in the evening - the whole day)
Log compiled from chat observations and structured with the assistance of Gemini AI.
05:56 – 06:33 — Only one fledgeling (Ziemowit with leg transmitter) is present in the nest. No parents visit during the early morning.
07:58 — The fledgeling gets soaked in the rain; water accumulates in the nest basin.
08:32 — The fledgeling departs from the nest despite the ongoing rain.
13:04 — The fledgeling returns from a nearby tree branch, chirping loudly as it spots an incoming adult.
13:05 — First Feeding (Male): The male parent arrives and delivers a generous portion of food. The fledgeling eats eagerly, leaving no food behind.
13:05 — The male parent departs.
14:36 — The fledgeling starts calling/chirping again as a parent approaches.
14:41 — Second Feeding (Female): The female parent arrives and regurgitates a large quantity of frogs. The fledgeling feeds until completely satiated, leaving crumbs in the nest.
14:42 — The female parent departs.
16:54 — Third Feeding (Male): The male parent arrives and delivers another substantial feeding consisting of numerous large frogs.
16:54 — The male parent departs immediately after feeding.
18:18 — The fledgeling exercises its wings and reacts to a live frog moving in the nest.
19:37 – Evening — The fledgeling remains alert in the nest, preening and resting in improving weather conditions.

Parental Foraging Strategy in Adverse Weather:
Adult black storks generally avoid foraging flights during heavy rain to prevent their plumage from becoming waterlogged. However, amphibian activity increases significantly immediately after rain, enabling the adults to catch and deliver large quantities of frogs in quick succession.
Post-Fledging Dependence & Survival Risks:
Fledgelings do not become independent immediately after their maiden flights. They continue to rely on parental feedings at the nest for 2–3 weeks to build up essential fat reserves.Maiden flights typically occur at around 65 days of age (range: 60–73 days), whereas final departure for migration occurs at an average of 87 days (range: 73–108 days).If a young stork is displaced or flushes from the nest prematurely, its chances of survival drop significantly. Without food and hydration, a fledgeling's physical condition degrades severely within 48 to 72 hours, hindering its ability to fly or learn to forage.
Telemetry Ring Readouts:
Electronic rings equipped with short-range loggers upload location data only when within close proximity (approx 200 m) of an active mobile network device (anyone with a mobile phone).
Local foresters conducted searches in nearby meadows to monitor the birds' presence.
(You can't see how much Mieszko lost, but it took the youngster a while to eat it, so there was a lot of it)
