4:21 PM@user-qd1ju1fp2c​​
Светлана, мы здорово заметили. да. это были аисты (Svetlana, we noticed great. Yes. they were storks)

4:26 PM@MKmatylda​​
@светлана you are right! Big shadows- must be stork

[marika.solo]

Gemini-chat helped me (in my opinion we observed more probably vulture shadow)

The Black Stork Shadow:

The "Cross" Shape: Storks always fly with their necks fully extended. Their shadow looks like a long, thin cross.
Proportions: The front part (head and neck) is very long and visible.
Movement: You will often see the shadow "flapping" its wings periodically.

The Griffon Vulture (Gyps fulvus) Shadow:

The "Flying Plank": Vultures have very short necks. Their shadow looks like a massive, thick rectangle or a "plank" with no head.
The "Fingers": You can see wide, separated feathers (primaries) at the tips of the wings in the shadow.
Movement: The shadow usually glides steadily in circles without any wing flapping.

There are waves today - we have a different shadow on the water:

- Distortion by waves: The shadow of a long-necked stork can become "fragmented" on the waves. If the waves are strong, the thin line of the neck in the shadow will disappear before the massive wings.
- Angle of the sun: In Spain, the sun is very high and harsh at certain times of day. The shadow then shortens, and details (such as the head) “disappear” beneath the massive surface of the wings.
- Flight speed: If the bird is flying in a direction opposite to the waves, the shadow appears jagged and indistinct.
