Oak tree nestbox slows down

There has been less activity in the oak tree nest box today. They have come in and out a few times, but often not bringing anything in, just sitting, looking around and then going out again…. is the nest finished? Is there now a quiet period before laying? As in the odd box, it doesn’t really look very ‘nest-like’ yet… I had thought that it would be more compacted and shaped. Here are a couple of screen shots from today.
