Key Takeaways:
Technical Disruption: The stream was offline for nearly three and a half hours (from 14:46:30 until 18:14:30).
Hydration and Material: Shortly after the broadcast resumed, the male showed active care by bringing grass to line the nest, followed by a quick return to deliver water to the chicks.
Parental Overlap: Both parents met at the nest at 18:36, leading to an abundant feeding session with large fish. The female returned for another short visit after 21:00 to deliver a late feeding.
CHICKS () ()
- 1st chick: 38 days old (hatched late evening 24.05)
- 2nd chick: 37 days old (hatched early morning 25.05)
- 3rd chick: 37 days old (hatched afternoon 25.05) Brood reduction by male
- 4th chick: 20 days old (hatched late evening 26.05)
- 5th chick: 17 days old (hatched afternoon 28.05)
prof. Zielinski (youtube chat info):
The direct cause was that male brought an insufficient amount of food, resulting in nutritional stress, which is the biological trigger that prompts adult birds to start the process of brood reduction.
Stork chicks grow exponentially. 90 days in the nest is like 18-21 years for humans. This means that 1 day in the nest is like almost 3 months for a human child. That is why their transformation is so amazing and fast.
