I had been up cleaning the house in the early hours of the morning getting ready for company flying in.  When taking a break I have sat on my front porch with the lights on.  A bird has flown thru the patio every time I have been on that patiio and sometimes more than once.  It appears to be the same bird.  Isn't this rather strange?

Hard to say without knowing a bit more.

Assuming it really is the same bird, then perhaps  your patio may be the most convenient "flight path" between two prominent perches  that this individual uses (e.g. as song perches for the "dawn chorus"). If so then it may fly through the patio about that time every morning, whether you are there or not! this is  - of course- pure speculation on my part !
