Tonight, I found the surviving fledgling on the large rock at the south end of the Promenade. It was being watched by its father, who picked up a rat and put it in a tree, where the fledgling came and took it.
The fledgling didn't eat much, but made lots of calls. It was as though it was waiting for its lost sibling to call back. Once the fledgling gave up on its meal, the father came in and finished it.
Graphic pictures of a rodent being eaten follow both in video and pictues, readers beware.
