Timeline of Events
Intruder Defense 08:57
The chicks spot an intruder near the nest (out of camera view). They react defensively by growling, heavy bill-tapping, and clapping.
Frustrated Begging 09:07
An adult stork flies nearby; chicks react with intense chirping, wing-flapping, and begging, but no parent lands to deliver food.
Similar false alarms occur at 09:35 AM and 10:13 AM.
Feeding 1 (Zica) 10:30
After heavy begging starting at 10:22 AM, Zica lands at 10:30:42 AM. She delivers a massive fish, which goes entirely to chick #3. Zica leaves quickly at 10:30:52 AM. Note: Her identity was verified via slow-motion playback, confirming her typical spot under the wing (by me).
Feeding 2 (Natalio) 11:21
Natalio arrives at 11:21:06 and successfully delivers the second feeding of the day to the brood.
Air Space Activity (Storks / Floatings) 14:57
At 14:57 and 15:01, large birds are seen spinning and flying around the quarry. Observers spot two birds at 15:05 - likely a territorial dispute involving "floaters" (young adult black storks looking to claim an existing nest site for future seasons).
Griffon Vulture Sighting 15:14
A very large bird passes by, casting a shadow on the water. Observers identify it as a Griffon Vulture (Gyps fulvus), too light and heavy for a black stork. Another vulture sighting possibly occurs at 15:44.
Intense Flight Training 18:36
Chicks #2 and #3 engage in heavy wing-flapping and jumping exercises. Observers note they are "entering a clinch" during their enthusiastic training sessions, exactly as they did yesterday.
Stork Reflection on Water 18:47
Maria notes a beautiful detail: at 18:47:31 (and again at 18:47:43), the reflection of a flying adult black stork is clearly visible gliding across the bottom section of the deep quarry water.
Evening Training Session 19:32 and next
The young storks continue their vigorous flight preparation into the late evening, demonstrating high energy levels.
Key Observations & Notes
- The Water & Hydration Debate:
A debate arose in the chat regarding parents bringing water. As clarified by me, this quarry nest benefits from a special microclimate due to the stone walls and a 40-meter deep body of water, which acts like a natural air conditioner. The chicks are healthy, safe in the shade after 14:00, and get their core hydration directly from food.
- Brood Development:
The young storks are nearly fully black, having lost almost all of their white down. They are energetic and expected to make their first fledging flights within 10–14 days.
- Daily Feeding Count:
Chat corrections confirmed that the brood was fed 2 times today (10:30 by Zica and 11:21 by Natalio), following a highly successful 5-feeding day yesterday.
