Several owls on New Years morning

My husband noticed 4 or 5 owls calling to each other at about 1am on New Years morning. We think they were tawnys. He copied their hoot and they all came nearer, one landing in a tree quite close to the back door. I was wondering if these would be a bunch of owls from the same nest still hanging around together as we’ve never heard more than 2 or 3 at the same time before. Is that right?
