It went to a rabbit hole, recently deserted as the young rabbits had left forever. However, the mother rabbit did not like that and attacked the owlet even though the hole was no longer in use.
The adult rabbit overthrew the young owl five times. It is not clear why the rabbit did that. A little owl parent tried to defend the youngster, but could do no more than hissing.
