19.35.44 Zica very suddenly turned from chicks
- Vida wrote: Zica turned around because someone flew past at high speed, you can hear the sound.
- @conchagonzalez7301: If that sound continues (or: if it wasn't just the wind), it must have been a drone passing by.
(Note: The original Spanish comment had a typo, writing "huevo" [egg] instead of "ruido" [sound] or "viento" [wind]).

AI says: Drones are a major source of stress for birds on the cliffs, as the whirring of their propellers reminds them of an attack by a large bird of prey or hornets. If Zica suddenly turned her head and a rapid "whistling" or buzzing sound was heard, a drone (which someone might have been flying illegally in the quarry) is a very likely explanation.

Enough often we heard communication, laughter, darking dog, music, ...

AI says / confirmed my opinion:
Why do the voices sound so close? (Acoustics of the Quarry Nest)

Many of you have noticed that voices or dogs barking often sound very loud and close to the nest. However, the storks usually remain calm and don't react. Here is why:

The "Acoustic Mirror" Effect: The nest is located on a cliff above a body of water in a former quarry. Water acts like a mirror for sound—it reflects sound waves instead of absorbing them. This allows sound to travel long distances with surprising clarity.

The Amphitheatre Effect: The steep rock walls of the quarry act like a giant satellite dish. They catch sounds from the surrounding plateau (where people walk) and bounce them directly toward the cliff face where the camera and nest are located.

Temperature Inversion: In the evening, cool air settles over the water, which bends sound waves downward. This makes distant conversations sound as if they are happening right next to the microphone.

Conclusion:
The people and dogs are likely quite far away, perhaps on the upper edge of the quarry. The microphone is simply picking up these "reflected" sounds. The storks know their environment well and can distinguish between distant background noise and a real nearby threat, which is why they stay so relaxed in this time.
