17:34:21 we see a bird in the water - a white head, impressively flapping its wings to get out of the water and onto the shore (unfortunately we don't see it in the camera shot)
B1C3 and Andrés Alfaro confirmed my opinion - we saw griffon vulture (Gyps fulvus).
Griffon vultures can end up in water, usually by accident (e.g., during migration, forced down by winds or harassment - e.g. gulls).
Let's hope this one made it to shore. It was waving impressively.
Andrés Alfaro:
Several nest in that area; just look at the feathers the storks bring. Sometimes inexperienced chicks fall into the water on their first flights.
Scenes like this are common in other parts of Spain, like Monfragüe.
It needs to reach a wide bank, even if it can climb out onto a ledge. To fly again, it has to take off with a little more height or run-up, otherwise it will fall again.
But yes, this is a 100% griffon vulture. It's clearly visible.
