The webcam on the Black vulture nest in the Sierra de Guadarrama was switched on again last week and everyone is happy to see the pair incubating one egg already. Watch it on you tube… 🙂
The chick has died at 8 days old and it seems that the cause was some kind of altercation between a parent and a stranger black vulture…. The video of the other one at the nest acting not particularly aggressive is here: At the end of the video you can see the chick is not moving.. maybe the parent trod on it accidentally?
