Curious owlet

The largest baby owl watches me walk around the yard in the mornings. When I talk to it, it bobs its head sideways… so cute! (see Facebook feed for video).  They have been a pretty quiet batch this year, which means they have been well fed. Yesterday a huge vulture was perched on top of the nest box. It scared the baby owls and we shooed it away. Being scavengers, it was unlikely it would attack, but you never know. Could it have been attracted by some uneaten rotting vermin in there?
