Tonight, the female came out of the cavity and was greeted by the male at the normal time.  The spent a few mintues together in the triangle above the bypass road. She returned to the nest and he went off into The Loch area.

We went down to The Loch area to look for him, without success, and returned to the cavity.  When we arrived both owls were out in the open, he soon took off and she went back inside. 

We could only guess as to what had happened while we were away.  It was unclear if food had been delivered.
